I am softly enforcing <linux/bitops.h> in the GPIO subsystem
because I think it's a great perceptual aid, I can skim code
faster if this is used, easier for the brain to handle and thus
simplifies maintenance.

Others may disagree on its virtues.

It is not a subjective opinion, but proving the point needs
perceptual psychology research.
