I was missing a very important thing.
<linux/gpio/driver.h> is used in various subsystems.
I tested only under drivers/gpio/, but drivers/pinctrl/ is one of the biggest source of compile errors.
(Probably I will get reports from kbuild test robot.)
So, I need to think about how to merge this (if the basic idea of this is OK).
Maybe,
[1] Send patches to subsystems (gpio, pinctrl, etc.) for v4.14 [2] Drop unneeded includes from linux/gpio/driver.h for v4.15
