In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was
the EC's dev pointer and not the keyboard's. Let's clean this up to
make it the keyboard's dev pointer. This could be useful in future
patches but also has the nice effect of changing a few printouts to
include the name of the keyboard device instead of the EC device, so we
will see:
[ 1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14
instead of:
[ 1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14

The bitwise shift operator has lower priority than plus operator. So the
values on macros should be enclosed in parentheses.
For example, "(1 << 4 + 1)" means "(1 << (4 + 1))", but it is not expected
by the macros.
And also fix other two coding style problems reported by
scripts/checkpatch.pl.

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.

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:194:12: error: 'imx_snvs_pwrkey_resume' defined but not used [-Werror=unused-function]

The spear keyboard driver uses #ifdef CONFIG_PM to hide its

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 changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver.
The driver already allows specifying what type of events (key / rel / abs)
a button generates when pressed, but for rel / abs axis we also need to
specify which value this specific gpio represents.
One use case is digital joysticks / direction-pads which are hooked up to
gpio, in this case we've left and right buttons which we want to map to
EV_ABS, ABS_X and we want generate events for left with a value of -1 and
for right with a value of +1 (and similar for up / down and ABS_Y).

The driver depends on GOLDFISH but there isn't a build dependency
so it's a good idea to allow the driver to be built even if that
option is disabled, if the COMPILE_TEST option is enabled.
That way, the driver can be built with a config generated by make
allyesconfig and can be checked if a patch would break the build.

The ChromeOS EC keyboard driver config depends on CROS_EC_PROTO but
MFD_CROS_EC selects CROS_EC_PROTO instead. Mixing select and depends
on is bad practice as it may lead to circular Kconfig dependencies.
Since the platform device that is matched with the keyboard driver
is registered by the ChromeOS EC mfd driver, KEYBOARD_CROS_EC really
should depend on MFD_CROS_EC. And because this config option selects
CROS_EC_PROTO, that dependency is met as well. So make the driver
to depend on MFD_CROS_EC instead of CROS_EC_PROTO.
