Hi Jamie

Minor point. I expect you can remove the header file gpio-fan.h.

There are also a few other headers files which can be removed, but i
suggest you do this in a separate cleanup patch. I think
ata_platform.h, input.h, leds.h, map.h, bridge-regs.h and maybe also
kirkwood.h are no longer needed.
