Throwing my can of paint into the mix...

I think it is more logical to first include the general <linux/gpio.h>,
followed by whatever <linux/gpio-foo.h> and <linux/gpio/bar.h>,
irrespective of (language-specific or phonebook) sort order.

Yeah, it sucks that this requires some manual work after running sort...
