Why not use INPUT_MC13783_PWRBUTTON to match the source file (and so
module) name.
Ok.

This implies GPL v2 only? So you either need to clearify here or you
need to adapt the MODULE_LICENSE line below to read

	MODULE_LICENSE("GPL v2");
Well, I took exactly the same license than the twl4030-pwrbutton. 
This driver is: MODULE_LICENSE("GPL"), why should I change it ?
So this driver is wrong, too. According to include/linux/module.h, "GPL"
means "GNU Public License v2 or later" and "GPL v2" means "GNU Public
License v2".

Why not use

	if (pdata->buttons)

to detect if the pwrbutton device should be registered?
To keep consistancy as the others sub-device are registered the same way 
(regulator, led). I can do it as you propose for the button but IMHO it's a 
bit strange to have a MC13XXX_USE_* for all the subdevice except the buttons. 
So should I change ?
It would be a third patch for your commit count to convert regulator and
led, too ;-)

Best regards
Uwe
