Subject: [PATCH 00/15] [Set 2/2] Rid W=1 issues from Input

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

This is the second (and last) of 2 sets.

Lee Jones (15):
input: joystick: xpad: Demote non-conformant kernel-doc header
input: keyboard: samsung-keypad: Remove set but unused variable 'var'
input: misc: mc13783-pwrbutton: File headers are not good candidates
for kernel-doc
input: touchscreen: goodix: Provide some missing function parameter
descriptions
input: touchscreen: imx6ul_tsc: Remove set but unused variable 'value'
input: touchscreen: melfas_mip4: Remove a bunch of unused variables
input: touchscreen: usbtouchscreen: Remove unused variable 'ret'
input: touchscreen: surface3_spi: Remove set but unused variable
'timestamp'
input: misc: wm831x-on: Source file headers are not good candidates
for kernel-doc
input: touchscreen: surface3_spi: Fix naming issue with
'surface3_spi_get_gpio_config's header
input: touchscreen: wm97xx-core: Provide missing description for
'status'
input: mouse: synaptics: Demote non-conformant kernel-doc header
input: touchscreen: goodix: Fix misspelling of 'ctx'
input: keyboard: applespi: Provide missing struct 'message'
descriptions
input: mouse: vmmouse: Demote obvious abuse of kernel-doc header

Yes. We can either convert the information to comments, or mark the
variables as __always_unused.

I'm assuming this would be passed on as MSC_TIMESTAMP?

I never found the time implementing this and I mask MSC_TIMESTAMP on most
devices anyway (except for Dell's i2c touchpads where I need it to work
around a fw bug). so at least from libinput's POV it wouldn't have any
effect either way.

Good morning Dmitry,

Are you planning on finishing this review?

About half of the patches are unreviewed and there are a couple of
open questions on others.

If __always unused suppresses this warning that would be my preference.
