I'll do short test. But... if you are right, your patch will just make
your machine refuse to suspend... right?

Ungood.

Actually, it seems to break suspend (returns  -EINVAL while refusing
to suspend), warnings are still there, and keyboard is dead after
failed suspend... double plus ungood.

Aha, so warning is solved: the one in the log is from gpio_buttons.

(I wonder if the 'unbalanced irq_wake' warning is useful... who added it?)
