__vlan_get_protocol_offset() has the wrong function name.
Fix that and all the other kdoc warnings in this file.

====================
net: dsa: cleanup EEE (part 2)
This is part 2 of the DSA EEE cleanups, removing what has become dead
code as a result of the EEE management phylib now does.
Patch 1 removes the useless setting of tx_lpi parameters in the
ksz driver.
Patch 2 does the same for mt753x.
Patch 3 removes the DSA core code that calls the get_mac_eee() operation.
This needs to be done before removing the implementations because doing
otherwise would cause dsa_user_get_eee() to return -EOPNOTSUPP.
Patches 4..8 remove the trivial get_mac_eee() implementations from DSA
drivers.
Patch 9 finally removes the get_mac_eee() method from struct
dsa_switch_ops.

Herbert also said : "In 2.6.19 we can eliminate the unnecessary

This patch consolidates things to have only two functions, with
a common prefix.
- netdev_watchdog_up(), exported for the sake of one freescale driver.
This replaces __netdev_watchdog_up() and dev_watchdog_up().
- netdev_watchdog_down(), static to net/sched/sch_generic.c

Similar to the earlier fixes meant for sm8x50 and x1e platforms,
we have to stop using the shared clk ops for sdm845 QUPs as well.
As Stephen Boyd pointed out in earlier fixes, there wasn't a problem
to mark QUP clks shared until we started parking shared RCGs at clk
registration time in commit 01a0a6cc8c ("clk: qcom: Park shared RCGs
upon registration"). Parking at init is actually harmful to the UART
when earlycon is used. If the device is pumping out data while the
frequency changes and we see garbage on the serial console until the
driver can probe and actually set a proper frequency.
This patch reverts the QUP clk sharing ops part of commit 06391eddb6
("clk: qcom: Add Global Clock controller (GCC) driver for SDM845"), so
that the QUPs on sdm845 don't get parked during clk registration and
break UART operations.

We've noticed that NFS can hang when using RPC over TLS on an unstable
connection, and investigation shows that the RPC layer is stuck in a tight
loop attempting to transmit, but forever getting -EBADMSG back from the
underlying network. The loop begins when tcp_sendmsg_locked() returns
-EPIPE to tls_tx_records(), but that error is converted to -EBADMSG when
calling the socket's error reporting handler.
Instead of converting errors from tcp_sendmsg_locked(), let's pass them
along in this path. The RPC layer handles -EPIPE by reconnecting the
transport, which prevents the endless attempts to transmit on a broken
connection.

scsi_execute_cmd() function can return both negative (linux codes) and
positive (scsi_cmnd result field) error codes.
Currently the driver just passes error codes of scsi_execute_cmd() to
hwmon core, which is incorrect because hwmon only checks for negative
error codes. This leads to hwmon reporting uninitialized data to
userspace in case of SCSI errors (for example if the disk drive was
disconnected).
This patch checks scsi_execute_cmd() output and returns -EIO if it's
error code is positive.

Currently, when the vdev start WMI cmd is sent from host, vdev related
parameters such as max_reg_power, max_power, and max_antenna_gain are
multiplied by 2 before being sent to the firmware. This is incorrect
because the firmware uses 1 dBm steps for power calculations.
This leads to incorrect power values being used in the firmware and
radio, potentially causing incorrect behavior.
Fix the update of max_reg_power, max_power, and max_antenna_gain values

Currently, the DFS CAC time and the usable state of the primary channel in
the channel definition are used to set the CAC_RUNNING flag for the ath12k
radio structure. However, this approach is flawed because there are channel
definitions where the primary channel is not a DFS channel, but the
secondary channel is. For example, in 5 GHz band, channel 36 with 160 MHz
bandwidth. In such cases, the flag is not set correctly and hence places
where this flag is tested will not operate as expected. For example, Rx
packets will not be dropped.
To fix this issue, use the cfg80211_chandef_dfs_usable() function from
cfg80211, which returns true if at least one channel is in a usable state.
This will ensure the CAC_RUNNING flag is set properly.
Additionally, update the CAC running debug log message to include the CAC
time in milliseconds and also print the center frequency segment 1.

The x86 shadow stack support has its own set of registers. Those registers
are XSAVE-managed, but they are "supervisor state components" which means
that userspace can not touch them with XSAVE/XRSTOR. It also means that
they are not accessible from the existing ptrace ABI for XSAVE state.
Thus, there is a new ptrace get/set interface for it.
The regset code that ptrace uses provides an ->active() handler in
addition to the get/set ones. For shadow stack this ->active() handler
verifies that shadow stack is enabled via the ARCH_SHSTK_SHSTK bit in the
thread struct. The ->active() handler is checked from some call sites of
the regset get/set handlers, but not the ptrace ones. This was not
understood when shadow stack support was put in place.
As a result, both the set/get handlers can be called with
XFEATURE_CET_USER in its init state, which would cause get_xsave_addr() to
return NULL and trigger a WARN_ON(). The ssp_set() handler luckily has an
ssp_active() check to avoid surprising the kernel with shadow stack
behavior when the kernel is not ready for it (ARCH_SHSTK_SHSTK==0). That
check just happened to avoid the warning.
But the ->get() side wasn't so lucky. It can be called with shadow stacks
disabled, triggering the warning in practice, as reported by Christina
Schimpe:

Ensure that shadow stacks are active in a thread before looking them up
in the XSAVE buffer. Since ARCH_SHSTK_SHSTK and user_ssp[SHSTK_EN] are
set at the same time, the active check ensures that there will be
something to find in the XSAVE buffer.

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
The current SDCA MBQ (Multi-Byte Quantities) register map only
supports 16-bit types, add support for more sizes and then update
the rt722 driver to use the new support. We also add support for
the deferring feature of MBQs to allow hardware to indicate it is
not currently ready to service a read/write.
Afraid I don't have hardware to test the rt722 change so it is
only build tested, but I thought it good to include a change to
demonstrate the new features in use.
In certain use-cases, a CRTC could switch between two encoders
and because the mode being programmed on the CRTC remains
the same during this switch, the CRTC's mode_changed remains false.
In such cases, the encoder's mode_set also gets skipped.
Skipping mode_set on the encoder for such cases could cause an issue
because even though the same CRTC mode was being used, the encoder
type could have changed like the CRTC could have switched from a
real time encoder to a writeback encoder OR vice-versa.
Allow encoder's mode_set to happen even when connectors changed on a
CRTC and not just when the mode changed.

Don't check for flat ccs from VF-level as VF does not have direct
access to the register.
If the BIOS disables FlatCCS support (a use-case that will nearly never
be used) and the has_flat_ccs flag is set, there shouldn't be
any functional impact. The hardware will drop writes to the CCS region,
and reads from the CCS region will always return 0.
For the native case, the flag is disabled if the BIOS disables
it to avoid unnecessary overhead in buffer object (BO) creation
and migration.

This is a general i2c controller feature. Some I2C devices may need the
I2C controller to remain active during resume_noirq() or suspend_noirq().
If the controller is autosuspended, there is no way to wake it up once
runtime PM disabled (in suspend_late()). During system resume, the I2C
controller will be available only after runtime PM is re-enabled
(in resume_early()). However, this may be too late for some devices.
Wake up the controller in the suspend() callback while runtime PM is
still enabled. The I2C controller will remain available until the
suspend_noirq() callback (pm_runtime_force_suspend()) is called. During
resume, the I2C controller can be restored by the resume_noirq() callback
(pm_runtime_force_resume()). Finally, the resume() callback re-enables
autosuspend. As a result, the I2C controller can remain available until
the system enters suspend_noirq() and from resume_noirq().

This add a imx7(d) specific compatible which is compatible to imx8mm.
This silences the dtbs_check warning:
arch/arm/boot/dts/nxp/imx/imx7s-mba7.dtb: dsi@30760000: compatible: 'oneOf' conditional failed, one must be fixed:
['fsl,imx7d-mipi-dsim', 'fsl,imx8mm-mipi-dsim'] is too long

There are no more board file users of this driver. The platform data
structure is only used internally. Two of the four fields it stores are
not used at all anymore. Pull the remainder into the driver data struct
and shrink code by removing parts that are now dead code.
