Would it not be better to add a followup patch replacing the removed
headers with something like:

  #ifndef __LINUX_GPIO_H
  #warn Don't include asm/gpio.h directly, include linux/gpio.h instead
  #endif

instead?  Perhaps even without the ifdef.  That will mean we still get
rid of the boilerplate and will encourage fixups to drivers, nothing
that hits these can be relying on a custom implementation since all the
headers concerned are boilerplate ones.
