A call to usb_set_interface() crashes if the device is deallocated
concurrently, such as due to physical removal or a serious IO error.
It could also interfere with other drivers using the device if the
current driver is unbound before the call is finished.
Document the need to delay driver unbinding until this call returns,
which solves both issues.
Document the same regarding usb_clear_halt(), which is equally known
to be routinely called by drivers.
Explicitly mention finishing pending operations in the documentation
of the driver disconnect callback.

The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values
in the ATA ID information to calculate cylinder and head values when
creating a CDB for READ or WRITE commands. The calculation involves
division and modulus operations, which will cause a crash if either of
these values is 0. While this never happens with a genuine device, it
could happen with a flawed or subversive emulation, as reported by the
syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if
either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID
information is 0. This requires isd200_Initialization() to return a
negative error code when initialization fails; currently it always
returns 0 (even when there is an error).

Currently xhci_map_urb_for_dma() creates a temporary buffer and copies
the SG list to the new linear buffer. But if the kzalloc_node() fails,
then the following sg_pcopy_to_buffer() can lead to crash since it
tries to memcpy to NULL pointer.
So return -ENOMEM if kzalloc returns null pointer.

DbC driver starts polling for events immediately when DbC is enabled.
The current polling interval is 1ms, which keeps the CPU busy, impacting
power management even when there are no active data transfers.
Solve this by polling at a slower rate, with a 64ms interval as default
until a transfer request is queued, or if there are still are pending
unhandled transfers at event completion.

Two NEC uPD720200 adapters have been observed to randomly misbehave:
a Stop Endpoint command fails with Context Error, the Output Context
indicates Stopped state, and the endpoint keeps running. Very often,
Set TR Dequeue Pointer is seen to fail next with Context Error too,
in addition to problems from unexpectedly completed cancelled work.
The pathology is common on fast running isoc endpoints like uvcvideo,
but has also been reproduced on a full-speed bulk endpoint of pl2303.
It seems all EPs are affected, with risk proportional to their load.
Reproduction involves receiving any kind of stream and closing it to
make the device driver cancel URBs already queued in advance.
Deal with it by retrying the command like in the Running state.

A trb_in_td() call is used to determine if a completion event matches
any TRB of the currently executing TD. This function is told to start
searching right after the last finished TD, which is not at all where
the currently expected TD is guaranteed to begin, because some TDs in
between may have been cancelled.
Not only is a pointless work performed, but a bug resulting in the HC
executing cancelled TDs was seen to trick the driver into associating
events from a TD just cancelled with an unrelated future TD.
Since the ring is being traversed for the specific purpose of finding
a match with the current TD, always start from its first TRB. This is
the most reliable bit of information that we posses.
Tracking of HC's work progress is not affected, except for cases when
a misattributed event would have moved dequeue past a pending TD.

Refactor the code to improve readability by using
'xhci_free_segments_for_ring()' function for freeing ring segments.
This replaces the custom while loop previously used within
'xhci_ring_expansion()' and 'xhci_alloc_segments_for_ring()'.
Slightly modify 'xhci_free_segments_for_ring()' to handle lists
which do not loop. This makes it possible to use it in error
paths of 'xhci_alloc_segments_for_ring()'.
This change also prepares for switching the custom xhci linked segment
list into to more standard list.h lists.

Slot ID is a index of a virtual device in struct 'xhci_hcd->devs[]'.
Previously, to get the slot ID associated with a port, we had to loop
through all devices and compare ports, which is very inefficient.
Instead, the slot ID (of the device which is directly connected to the
port), is added to the its corresponding 'xhci_port' struct. As a result,
finding the port's device is quick and easy.
Function 'xhci_find_slot_id_by_port()' is removed, as it is no longer
needed.

Variables real & fake port do not convey their purpose, thus they are
replaced with a pointer to the root hub port 'struct xhci_port *rhub_port'.
'rhub_port' contains real & fake ports in zero-based format, which happens
to be more widely used inside the xHCI driver:
- 'real_port' is ('rhub_port->hw_portnum' + 1)
- 'fake_port' is ('rhub_port->hcd_portnum' + 1)
One reason for real port being one-based, is to signal other functions in
case struct 'xhci_virt_device' initialization failed, in this case the
value will remain 0. This is no longer needed, instead we check whether
or not 'rhub_port' is 'NULL'.

xHC hardware needs to know which roothub port a USB device is attached to
when controlling the device, so the xHCI driver stores in each device the
roothub port which it's connected behind. This is done with two different
port index values, the 'real_port' which is an index to the xHC hardware
port register array, and the 'fake_port' which is the per hub port index
used by the hub driver.
Instead of finding real & fake port separately, find the root hub port
'xhci_port' structure which contains both real & fake port values:
- 'real_port' is ('hw_portnum' + 1)
- 'fake_port' is ('hcd_portnum' + 1)
i.e. real & fake port are 'hw_portnum' & 'hcd_portnum' in one-based
format.
The 'xhci_port' structure is a better way to refer to roothub ports than
the 'real_port' & 'fake_port'. As a result, these port indexes are slated
to be replaced with a direct pointer to the root hub port. This patch
setups the ground work for the future changes.

typec_class to be declared at build time placing them into read-only

...
========
- Added new MHI_PM_SYS_ERR_FAIL state to the MHI state machine to properly
cleanup the channel state if the device fails to respond to the MHI reset
during SYS_ERR handling. This issue was discovered with the Qualcomm AIC100 AI
accelerator device.
- Modified the code that reads and exposes the OEM_PK_HASH registers through
sysfs to read them on-demand instead of reading once during boot. Qualcomm
AIC100 devices support provisioning the keys dynamically, so this allows the
users to know the upto date information.
- Added tracepoint support to expose the debug information over tracefs.
- Reverted the commit that reads the MHI device revision from the device during
boot. This is done because the read info was not used anywhere (dead code) and
also it is not possible to read the revision info from all the devices.
- Constified the modem config for Telit FN980 modem as required by the MHI core.
MHI Endpoint
============
- Replaced kzalloc() with kcalloc() in an effort to avoid integer overflows
during multiplication. Even though there is no potential overflow in the
endpoint code, this is done for the sake of uniformity and best practice.
- Fixed the kmem_cache_create() failure check to use the correct variable.

The desired DT pattern for clock indexing is the following:
clocks = <&gcc GCC_CAMERA_AHB_CLK>,
<&bi_tcxo_div2>,
<&bi_tcxo_ao_div2>,
<&sleep_clk>;
In order to facilitate that indexing structure we need to have DT_IFACE
enum defined.

In commit 19416123ab ("block: define 'struct bvec_iter' as packed"),
what we need is to save the 4byte padding, and avoid `bio` to spread on
one extra cache line.
It is enough to define it as '__packed __aligned(4)', as '__packed'
alone means byte aligned, and can cause compiler to generate horrible
code on architectures that don't support unaligned access in case that
bvec_iter is embedded in other structures.

The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.
This commit converts dm-verity from tasklet to BH workqueue. It
backfills tasklet code that was removed with commit 0a9bab391e
("dm-crypt, dm-verity: disable tasklets") and tweaks to use BH
workqueue (and does some renaming).
This is a minimal conversion which doesn't rename the related names
including the "try_verify_in_tasklet" option. If this patch is applied, a
follow-up patch would be necessary. I couldn't decide whether the option

[snitzer: rename 'use_tasklet' to 'use_bh_wq' and 'in_tasklet' to 'in_bh']
Signed-off-by: Mike Snitzer <snitzer@kernel.org>
The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.
This commit converts dm-crypt from tasklet to BH workqueue. It
backfills tasklet code that was removed with commit 0a9bab391e
("dm-crypt, dm-verity: disable tasklets") and tweaks to use BH
workqueue.
Like a regular workqueue, a BH workqueue allows freeing the currently
executing work item. Converting from tasklet to BH workqueue removes the
need for deferring bio_endio() again to a work item, which was buggy anyway.
I tested this lightly with "--perf-no_read_workqueue
--perf-no_write_workqueue" + some code modifications, but would really
-appreciate if someone who knows the code base better could take a look.

Meson8 pwm type always has 4 input clocks. Some inputs may be grounded,
like in the AO domain of some SoCs.
Drop the parent number parameter and make this is constant.
This is also done to make the addition of generic meson8 compatible easier.

The binding that is used up to now describe which input the PWM
channel multiplexer should pick among its possible parents,
which are hardcoded in the driver. This isn't a good binding in
the sense that it should describe hardware but not usage.
Add a new binding deprecating the old one that uses clocks in a
better way and how clocks are usually used today: The list of
clocks describe the inputs of the PWM block as they are realised
in hardware.
So deprecate the old bindings and introduce a compatible per SoC
family to replace these.

s4 has been added to the compatible list while converting the Amlogic PWM
binding documentation from txt to yaml.
However, on the s4, the clock bindings have different meaning compared to
the previous SoCs.
On the previous SoCs the clock bindings used to describe which input the
PWM channel multiplexer should pick among its possible parents.
This is very much tied to the driver implementation, instead of describing
the HW for what it is. When support for the Amlogic PWM was first added,
how to deal with clocks through DT was not as clear as it nowadays.
The Linux driver now ignores this DT setting, but still relies on the
hard-coded list of clock sources.
On the s4, the input multiplexer is gone. The clock bindings actually
describe the clock as it exists, not a setting. The property has a
different meaning, even if it is still 2 clocks and it would pass the check
when support is actually added.
Also the s4 cannot work if the clocks are not provided, so the property is
no longer optional.
Finally, for once it makes sense to see the input as being numbered
somehow. No need to bother with clock-names on the s4 type of PWM.

Just simply reordering the functions mlx5e_ptp_metadata_map_put and
mlx5e_ptpsq_track_metadata in the mlx5e_txwqe_complete context is not good
enough since both the compiler and CPU are free to reorder these two
functions. If reordering does occur, the issue that was supposedly fixed by
7e3f3ba97e ("net/mlx5e: Track xmit submission to PTP WQ after populating
metadata map") will be seen. This will lead to NULL pointer dereferences in
mlx5e_ptpsq_mark_ts_cqes_undelivered in the NAPI polling context due to the
tracking list being populated before the metadata map.

The packet number attribute of the SA is incremented by the device rather
than the software stack when enabling hardware offload. Because the packet
number attribute is managed by the hardware, the software has no insight
into the value of the packet number attribute actually written by the
device.
Previously when MACsec offload was enabled, the hardware object for
handling the offload was destroyed when the SA was disabled. Re-enabling
the SA would lead to a new hardware object being instantiated. This new
hardware object would not have any recollection of the correct packet
number for the SA. Instead, destroy the flow steering rule when
deactivating the SA and recreate it upon reactivation, preserving the
original hardware object.

Functions which can't access MFRL (Management Firmware Reset Level)
register, have no use of fw_reset structures or events. Remove fw_reset
structures allocation and registration for fw reset events notifications
for these functions.
Having the devlink param enable_remote_dev_reset on functions that don't
have this capability is misleading as these functions are not allowed to
influence the reset flow. Hence, this patch removes this parameter for
such functions.
In addition, return not supported on devlink reload action fw_activate
