Input: wm97xx: Simplify resource management

2022-01-31T13:17:24+00:00

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.

Loading then unloading wm97xx-ts.ko when CONFIG_AC97_BUS=m
causes a WARNING: from drivers/base/driver.c:

Unexpected driver unregister!
WARNING: CPU: 0 PID: 1709 at ../drivers/base/driver.c:193 driver_unregister+0x30/0x40

Fix this by only calling driver_unregister() with the same
condition that driver_register() is called.

As we move stuff around, some doc references are broken. Fix some of
them via this script:

Manually checked if the produced result is valid, removing a few
false-positives.

Input: wm97xx: add new AC97 bus support

2017-09-19T16:07:28+00:00

This adds support for the new AC97 bus code, which discovers the devices
rather than uses platform data.

As part of this discovery, it enables a multi-function device wm97xx,
which supports touchscreen, battery, ADC and an audio codec. This patch
adds the code to bind the touchscreen "cell" as the touchscreen driver.

This was tested on the pxa architecture with a pxa270 + wm9713 + the
mioa701 touchscreen.

Input: wm97xx: split out touchscreen registering

2017-09-19T16:04:54+00:00

wm97xx-core does several things in it initialization :
 - touchscreen input device setup
 - battery device creation

As the wm97xx is actually a multi-function device handling an audio
codec, a touchscreen, a gpio block and an ADC, reshape the probing to
isolate what is truly input/touchscreen specific from the remaining
part.

This is only code shuffling, there is no functional change.

Input: wm97xx - make missing platform data non-fatal

2017-01-24T18:27:34+00:00

Commit 6480af4915d6 ("power_supply: wm97xx_battery: use
power_supply_get_drvdata") made wm97xx platform data mandatory, although
it's still optional.

This patch fixes an oops during driver probe on one of my MIPS boards with
a wm9712.
