For devm-managed input devices we should not modify input device's parent,
otherwise automatic release of resources will not work properly.

Returning ret is wrong. And checking for an error as well. User space

commit 21fb9f0d5e91 ("Input: twl6040-vibra - use system workqueue")
says that it switches to use the system workqueue but it did neither
- remove the workqueue struct variable
- replace code to really use the system workqueue
Instead it calls queue_work() on uninitialized info->workqueue.
The result is a NULL pointer dereference in vibra_play().
Solution: use schedule_work

The trigger delay algorithm that converts from microseconds to
the register value looks incorrect. According to most of the PMIC
documentation, the equation is
delay (Seconds) = (1 / 1024) * 2 ^ (x + 4)
except for one case where the documentation looks to have a
formatting issue and the equation looks like
delay (Seconds) = (1 / 1024) * 2 x + 4
Most likely this driver was written with the improper
documentation to begin with. According to the downstream sources
the valid delays are from 2 seconds to 1/64 second, and the
latter equation just doesn't make sense for that. Let's fix the
algorithm and the range check to match the documentation and the
downstream sources.

We shouldn't assign the parent device of the input_dev to be the
parent MFD device, because this will be used for devres which causes
input_unregister_device to run after the haptics device has been
removed, since it is itself a child of the MFD device. The default
of using the haptics device itself as the parent is correct.

This adds the VID/PID combination for the Xbox One version of the Mad
Catz FightStick TE 2.
The functionality that this provides is about on par with what the
Windows drivers for the stick manage to deliver.
What works:
- Digital stick
- 6 main buttons
- Xbox button
- The two buttons on the back
- The locking buttons (preventing accidental Xbox button press)
What doesn't work:
- Two of the main buttons (don't work on Windows either)
- The "Haptic" button setting does not have an effect (not sure if it
works on Windows)
I added the MAP_TRIGGERS_TO_BUTTONS option but in my (limited) testing
there was no practical difference with or without. The FightStick does
not have triggers though so adding it makes sense.

The gtco driver expects at least one valid endpoint. If given malicious
descriptors that specify 0 for the number of endpoints, it will crash in
the probe function. Ensure there is at least one endpoint on the interface
before using it.
Also let's fix a minor coding style issue.

Synaptics uses the Register Mapped Interface (RMI) protocol as a
communications interface for their devices. This driver adds the core
functionality needed to interface with RMI4 devices.
RMI devices can be connected to the host via several transport protocols
and can supports a wide variety of functionality defined by RMI functions.
Support for transport protocols and RMI functions are implemented in
individual drivers. The RMI4 core driver uses a bus architecture to
facilitate the various combinations of transport and function drivers
needed by a particular device.

The X/Y position measurements read from the controller are interpreted
wrong. The first measurement X+ contains the Y position, and the second
measurement Y+ the X position (see also Table 11 Register Table in the
data sheet).
The problem is already known and a swap option has been introduced:
commit 6680884a4420 ("Input: ad7879 - add option to correct xy axis")
However, the meaning of the new boolean is inverted since the underlying
values are already swapped. Let ts->swap_xy set to true actually be the
swapped configuration of the two axis.

When changing the scan rate as part of runtime-resume process we may lose
some of the events, because:
1) for gen3 trackpads, the driver must msleep() some time to ensure that
the device is ready to accept next command;
2) for gen5 and later trackpads, the queue dumping function will simply
ignore the events when waiting for the set power mode command response.
The solution is to keep polling and report those valid events when the set
power mode command is in progress.

A dependency on ARCH_SHMOBILE seems to be the best option for sh_keysc:
* For Super H based SoCs: sh_keysc is used on SH_MIGOR, SH_ECOVEC, SH_KFR2R09,
SH_7722_SOLUTION_ENGINE, and SH_7724_SOLUTION_ENGINE, which depend on
either CPU_SUBTYPE_SH7722 or CPU_SUBTYPE_SH7724, and both select
ARCH_SHMOBILE.
* For ARM Based SoCs: Since the removal of legacy (non-multiplatform) support
this driver has not been used by any Renesas ARM based SoCs. The Renesas
ARM based SoCs currently select ARCH_SHMOBILE, however, it is planned
that this will no longer be the case.
This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

This changes how the used gpios are stored (i.e. a struct gpio_descs
instead of two struct gpio_desc) and as with >2 gpios the states are
numbered differently the function rotary_encoder_get_state returns
unencoded numbers instead of grey encoded numbers before. The latter has
some implications on how the returned value is used and so the change is
bigger than one might expect at first.

Drop support for platform data passed via a C-structure and switch to
device properties instead, which should make the driver compatible with all
platforms: OF, ACPI and static boards. Static boards should use property
sets to communicate device parameters to the driver.

commit e4b88e19897f1039fd83f1630517becafc0dd163
"Input: stmpe-ts - enforce device tree only mode"
removed platform data but accidentally stripped away useful
kerneldoc, so reintroduce it.

The SNVS power key driver has suspend/resume functions that
are accessed using SIMPLE_DEV_PM_OPS, which hide the reference
when CONFIG_PM_SLEEP is not set, resulting in a warning about
unused functions:
drivers/input/keyboard/snvs_pwrkey.c:183:12: error: 'imx_snvs_pwrkey_suspend' defined but not used [-Werror=unused-function]
drivers/input/keyboard/snvs_pwrkey.c:194:12: error: 'imx_snvs_pwrkey_resume' defined but not used [-Werror=unused-function]
This adds __maybe_unused annotations to let the compiler know
it can silently drop the function definition.

The spear keyboard driver uses #ifdef CONFIG_PM to hide its
power management functions, but then uses references from
SIMPLE_DEV_PM_OPS that are only present if both CONFIG_PM
and CONFIG_PM_SLEEP are set, resulting in a warning about unused
functions:
drivers/input/keyboard/spear-keyboard.c:292:12: error: 'spear_kbd_suspend' defined but not used [-Werror=unused-function]
drivers/input/keyboard/spear-keyboard.c:345:12: error: 'spear_kbd_resume' defined but not used [-Werror=unused-function]
This removes the #ifdef and instead uses a __maybe_unused
annotation.
