Same is true for gpiolib-cdev, btw.
You want to touch that one up as well?

Yeah, but that is indirect, and gpiolib-cdev.c uses struct notifier_block
directly.  Doesn't that warrant an explicit include?

Then gpiolib.c would need one too. IMO it's fine to just have it in
gpiolib.h. It's a gpio-local header included by all core .c files.

Can you also sort them (maybe in a separate change)?
