Seems some headers are missing. The rule of thumb is to include
headers the code uses directly.
Moreover, using a "proxy" header is not the best idea.

kernel.h // ARRAY_SIZE()
mod_devicetable.h // of_device_id
module.h
platform_device.h

pinctrl/pinctrl.h

With the above, it might be that existing inclusions become unused, so
drop them in such a case.

+ trailing comma. The rule of thumb is to add a comma when it's not a
terminator entry.
