Arnd Bergmann 979987ded3 Input: ektf2127 - mark PM functions as __maybe_unused ...

The newly added ektf2127 driver uses the SIMPLE_DEV_PM_OPS macro
to conditionally refer to the resume/suspend functions, which
causes a warning when CONFIG_PM_SLEEP is disabled:

drivers/input/touchscreen/ektf2127.c:168:12: error: 'ektf2127_resume' defined but not used [-Werror=unused-function]
drivers/input/touchscreen/ektf2127.c:156:12: error: 'ektf2127_suspend' defined but not used [-Werror=unused-function]

We could either put these functions inside of an #ifdef or
add __maybe_unused annotations. This uses the second approach,
which is generally more foolproof.
