apmf_sbios_heartbeat_notify()
The kfree() function was called in one case by
the apmf_sbios_heartbeat_notify() function during error handling
even if the passed variable contained a null pointer.
This issue was detected by using the Coccinelle software.
* Thus return directly after a call of the function “apmf_if_call” failed
at the beginning.
* Delete the label “out” which became unnecessary with this refactoring.

This commit adds a hotkey to switch between "gamepad" mode (mouse and keyboard
disabled) and "desktop" mode (gamepad disabled) by holding down the options
button (mapped here as the start button). This mirrors the behavior of the
official Steam client.
This also adds and uses a function for generating haptic pulses, as Steam also
does when engaging this hotkey.

SDL includes a list of settings (formerly called registers in this driver),

Valve. This commit imports a significant chunk of that list as well as

replaces bitmask definitions that used hex with the BIT macro.

The client_opened variable was used to track if the hidraw was opened by any
clients to silence keyboard/mouse events while opened. However, there was no
counting of how many clients were opened, so opening two at the same time and
then closing one would fool the driver into thinking it had no remaining opened
clients.

This cleans up the locking logic so that the spinlock is consistently used for
access to a small handful of struct variables, and the mutex is exclusively and
consistently used for ensuring that mutliple threads aren't trying to
send/receive reports at the same time. Previously, only some report
transactions were guarded by this mutex, potentially breaking atomicity. The
mutex has been renamed to reflect this usage.

The original implementation of this driver incorrectly guessed the function of
this register. It's not only unnecessary to write to this register for lizard

value was intentionally set, for example by Steam.

Currently, each trip point defined in the device tree corresponds to a
single hardware interrupt. This commit instead switches to using two
hardware interrupts, whose values are set dynamically using the
set_trips callback. Additionally, the critical temperature threshold is
handled specifically.
Setting interrupts in this way also fixes a long-standing lockdep
warning, which was caused by calling thermal_zone_get_trips with our
lock being held. Do note that this requires TMU initialization to be
split into two parts, as done by the parent commit: parts of the
initialization call into the thermal_zone_device structure and so must
be done after its registration, but the initialization is also
responsible for setting up calibration, which must be done before
thermal_zone_device registration, which will call set_trips for the
first time; if the calibration is not done in time, the interrupt values
will be silently wrong!

This will be needed in the future, as the thermal zone subsystem might
call our callbacks right after devm_thermal_of_zone_register. Currently
we just make get_temp return EAGAIN in such case, but this will not be
possible with state-modifying callbacks, for instance set_trips.

Exynos 4210 supports setting a base threshold value, which is added to
all trip points. This might be useful, but is not really necessary in
our usecase, so we always set it to 0 to simplify the code a bit.
Additionally, this change makes it so that we convert the value to the
calibrated one in a slightly different place. This is more correct
morally, though it does not make any change when single-point
calibration is being used (which is the case currently).

Currently, the default mechanism is to trigger a shutdown after the
critical temperature is reached.
In some embedded cases, such behavior does not suit well, as the board may
be unattended in the field and rebooting may be a better approach.
The bootloader may also check the temperature and only allow the boot to
proceed when the temperature is below a certain threshold.
Introduce support for allowing a reboot to be triggered after the
critical temperature is reached.
If the "critical-action" devicetree property is not found, fall back to
the shutdown action to preserve the existing default behavior.
If a custom ops->critical exists, then it takes preference over
critical-actions.
Tested on a i.MX8MM board with the following devicetree changes:
thermal-zones {
cpu-thermal {
critical-action = "reboot";
};

The new cleanup.h facilities that arrived in v6.5-rc1 can replace the
the usage of devm semantics in acpi_nfit_init_interleave_set(). That
routine appears to only be using devm to avoid goto statements. The
new __free() annotation at variable declaration time can achieve the same
effect more efficiently.
There is no end user visible side effects of this patch, I was
motivated to send this cleanup to practice using the new helpers.

This patch adds support for each available OTP variant of the device.
The OTP configuration cannot be read over I2C, so it is derived from
a compatible string instead.
Early revisions of the D0 order code require their OTP-enabled func-
tionality to be manually restored following a soft reset; this patch
accommodates this erratum as well.

This patch adds support for slider gestures that can be expressed
by the device. Each gesture (e.g. tap or hold) can be mapped to a
unique keycode for either slider 0 or 1.
With this change, raw slider coordinates are reported only if the
slider has no keycodes defined. This prevents unwanted mouse cur-
sor movement when expressing axial gestures (e.g. swipe) and also
eliminates some unnecessary I2C traffic.
Different revisions of silicon use different tap and swipe timeout
step sizes. Apply an appropriate scaling factor depending on which
revision is found.
To facilitate this change, store the iqs269_ver_info struct in the
driver's private data so that other functions can use it after the
driver has probed.
Last but not least, a former reserved field in iqs269_ver_info now
contains useful information; give it a name (fw_num).

There are a few PHY drivers that can handle SFP modules through their
sfp_upstream_ops. Introduce Phylib helpers to keep track of connected
SFP PHYs in a netdevice's namespace, by adding the SFP PHY to the
upstream PHY's netdev's namespace.
By doing so, these SFP PHYs can be enumerated and exposed to users,
which will be able to use their capabilities.

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to.

The __of_mdiobus_register() function was storing the device node in
dev.of_node without increasing its reference count. It implicitly relied
on the caller to maintain the allocated node until the mdiobus was
unregistered.
Now, __of_mdiobus_register() will acquire the node before assigning it,
and of_mdiobus_unregister_callback() will be called at the end of
mdio_unregister().
Drivers can now release the node immediately after MDIO registration.
Some of them are already doing that even before this patch.

IIO: 2nd set of new device support, features and cleanup for 6.8
A late/optimistic second pull request. The bots have been poking them
since Wednesday without any issues. There are a few fixes in the
ad7091r5 driver as part of rework to enable the ad7091r8 parts that
are included at start of that series.
Includes pre-work for major changes to the DMA buffers that should
land in 6.9 and will greatly improve performance and flexibility for
high performance devices by enabling DMABUF based zero copy transfers
when we don't need to bounce the data via user space.
New device support
------------------
adi,ad7091r8
- Major refactor of existing adi,ad7091r5 driver to separate out useful
shared library code that can be used by I2C and SPI parts.
- Use that library from a new driver supporting the AD7091R-2, AD7091R-4
and AD7091R-8 12-Bit SPI ADCs.
- Series includes some late breaking fixes for the ad7091r5.
microchip,mcp4821
- New driver for MCP4801, MCP4802, MCP4811, MCP4812, MCP4821 and MCP4822
I2C single / dual channel DACs.
Cleanup
-------
buffers:
- Use IIO_SEPARATE in place of some hard-coded 0 values.
dma-buffers:
- Simplify things to not use an outgoing queue given it only ever has
up to two elements and we only need to track which is first.
- Split the iio_dma_buffer_fileio_free() function up to make it easier
to read and enable reuse in a series lining up for 6.9
iio.h
- Drop some stale documentation of struct fields that don't exist.
