Since commit 1f2bcb8c8c ("gpio: protect the descriptor label with

a "sleeping in atomic context" smatch warning.
This function (along with gpiod_get/put() and all other GPIO APIs apart
from gpiod_get/set_value() and gpiod_direction_input/output()) should
have never been called with a spinlock taken. We're only fixing this now
as GPIOLIB has been rebuilt to use SRCU for access serialization which
uncovered this problem.
Move the calls to gpiod_get/put() outside the spinlock critical section.

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).

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.

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.

This replaces the custom while loop previously used within

Slightly modify 'xhci_free_segments_for_ring()' to handle lists
which do not loop. This makes it possible to use it in error

This change also prepares for switching the custom xhci linked segment

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.

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.

This includes following USB4/Thunderbolt changes for the v6.9 merge
window:
- Reset the topology also for USB4 v1 routers on driver load
- DisplayPort tunneling and bandwidth allocation mode improvements
- Tracepoint support for the control channel
- Couple of minor fixes and cleanups.
All these have been in linux-next with no reported issues.

========
- 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.
