Two spaces? It's tabs! Btw, it's for good looking formatting and
it was taken from pxa-regs.h. I'd like to preserve it like it is.

I'm sure I know what I'm doing, right here it preserves modifier between
two function calls, i.e. scan_keys(1, ...); scan_keys(0, ...);

Why the heck you want to reset here? It's not fatal. We can handle this

Sorry, left it occasionally.
