[PATCH v5 0/5] Input/HID: Consolidate ChromeOS Vivaldi keyboard logic

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

This is a follow-on to this thread[1] where we discussed the need to
support the vivaldi keyboard function row keys in the google hammer
driver. I've extracted the common code into a new vivaldi-fmap.c file
that can be used by the various keyboard drivers used on ChromeOS
devices to expose the function_row_physmap sysfs attribute. Then we make
another file to keep the HID parsing logic common for the vivaldi and
hammer keyboards. Finally, we add support for the function row physmap
attribute to the hammer driver.

NOTE: I dropped Tested-by and Acked-by as patches have been reworked,
please give them another spin.

Changed from v4 (dtor):
(https://lore.kernel.org/r/20220216195901.1326924-1-swboyd@chromium.org):
 * The series is on top of [PATCH] HID: vivaldi: fix sysfs attributes
   leak (https://lore.kernel.org/r/YhmAAjNeTjiNoLlJ@google.com)
 * Added patch to used devm for keyboard backlight LED in hammer driver
 * Avoid putting HID-specific stuff in input header, instead introduce
   new private hid-vivaldi-common.h
 * More code sharing between hid-google-hammer.c and hid-vivaldi.c by
   mandating that vivaldi data instance should be the very first or the
   only driver-private data.
