wm97xx_remove() returns zero unconditionally. To prepare changing the
prototype for platform remove callbacks to return void, make it explicit
that wm97xx_mfd_remove() always returns zero.
The prototype for wm97xx_remove cannot be changed, as it's also used as
a plain device remove callback.

wait_for_completion_timeout() returns unsigned long not int.
It returns 0 if timed out, and positive if completed.
The check for <= 0 is ambiguous and should be == 0 here
indicating timeout which is the only error case.

Add a sanity check on the device id-table driver_info field to make sure
we never access a type structure (and function pointers) outside of the
device info array (e.g. if someone fails to ifdef a device-id entry).
Note that this also suppresses a compiler warning with -Warray-bounds
(gcc-11.3.0) when compile-testing the driver without enabling any of
the device type Kconfig options:

According to Ilitek "231x & ILI251x Programming Guide" Version: 2.30
"2.1. Power Sequence", "T4 Chip Reset and discharge time" is minimum
10ms and "T2 Chip initial time" is maximum 150ms. Adjust the reset
timings such that T4 is 12ms and T2 is 160ms to fit those figures.
This prevents sporadic touch controller start up failures when some
systems with at least ILI251x controller boot, without this patch
the systems sometimes fail to communicate with the touch controller.

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Pull spi updates from Mark Brown:
"The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus
types, causing updates to most SPI device drivers. The branch with
that on has been cross merged with a couple of other trees which added
new SPI drivers this cycle, I'm not expecting any build issues
resulting from the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than
numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.

Add support for the IST3038C touchscreen IC from Imagis, based on
downstream driver. The driver supports multi-touch (10 touch points)
The IST3038C IC supports touch keys, but the support isn't added
because the touch screen used for testing doesn't utilize touch keys.
Looking at the downstream driver, it is possible to add support
for other Imagis ICs of IST30**C series.

VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

I observed the following problem with the BT404 touch pad
running the Phosh UI:
When e.g. typing on the virtual keyboard pressing "g" would
produce "ggg".
After some analysis it turns out the firmware reports that three
fingers hit that coordinate at the same time, finger 0, 2 and
4 (of the five available 0,1,2,3,4).
DOWN
Zinitix-TS 3-0020: finger 0 down (246, 395)
Zinitix-TS 3-0020: finger 1 up (0, 0)
Zinitix-TS 3-0020: finger 2 down (246, 395)
Zinitix-TS 3-0020: finger 3 up (0, 0)
Zinitix-TS 3-0020: finger 4 down (246, 395)
UP
Zinitix-TS 3-0020: finger 0 up (246, 395)
Zinitix-TS 3-0020: finger 2 up (246, 395)
Zinitix-TS 3-0020: finger 4 up (246, 395)
This is one touch and release: i.e. this is all reported on
touch (down) and release.
There is a field in the struct touch_event called finger_cnt
which is actually a bitmask of the fingers active in the
event.
Rename this field finger_mask as this matches the use contents
better, then use for_each_set_bit() to iterate over just the
fingers that are actally active.
Factor out a finger reporting function zinitix_report_fingers()
to handle all fingers.
Also be more careful in reporting finger down/up: we were
reporting every event with input_mt_report_slot_state(..., true);
but this should only be reported on finger down or move,
not on finger up, so also add code to check p->sub_status
to see what is happening and report correctly.
After this my Zinitix BT404 touchscreen report fingers
flawlessly.
The vendor drive I have notably does not use the "finger_cnt"
and contains obviously incorrect code like this:
if (touch_dev->touch_info.finger_cnt > MAX_SUPPORTED_FINGER_NUM)
touch_dev->touch_info.finger_cnt = MAX_SUPPORTED_FINGER_NUM;
As MAX_SUPPORTED_FINGER_NUM is an ordinal and the field is
a bitmask this seems quite confused.

Because there is no way to detect if the touchscreen has pen support,
the driver is allocating and registering the input_pen input_dev on
receiving the first pen event.
But this means that the input_dev gets allocated after the request_irq()
call which means that the devm framework will free it before disabling
the irq, leaving a window where the irq handler may run and reference the
free-ed input_dev.
To fix this move the allocation of the input_pen input_dev to before
the request_irq() call, while still only registering it on the first pen
event so that the driver does not advertise pen capability on touchscreens
without it (most goodix touchscreens do not have pen support).

Use the new input_copy_abs() helper and move the 2 input_abs_set_res()
calls up to be directly after the 2 input_copy_abs() calls, so that
the calls initializing the X and Y axis are all together.

Interrupt() resource
ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular
GPIO ACPI resource in their ACPI tables.
Some CHT devices have a bug, where the also is bogus interrupt resource
(likely copied from a previous Bay Trail based generation of the device).
The i2c-core-acpi code will assign the bogus, non-working, interrupt
resource to client->irq. Add a workaround to fix this up.

This driver works just fine with the BT404 version of the touchscreen
as well. Tested on the Samsung GT-I8160 (Codina) mobile phone.
Add all the new variants from the binding document so people can
easily test them, we believe most of them work more or less.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

ASoC: Fixes for v5.17
Quite a few fixes here, including an unusually large set in the core
spurred on by various testing efforts as well as the usual small driver
fixes. There are quite a few fixes for out of bounds writes in both the
core and the various Qualcomm drivers, plus a couple of fixes for
locking in the DPCM code.

Since the commit in the Fixes tag below, 'wm->input_dev' is a managed
resource that doesn't need to be explicitly unregistered or freed (see
devm_input_allocate_device() documentation)
So, remove some unless line of code to slightly simplify it.
