I thought I would be a good enough programmer to not need build tests.
Obviously I was wrong and introduced build problems with the following
patches:

	input: touchscreen: tsc200x: Make tsc200x_remove() return void
	mfd: mc13xxx: Make mc13xxx_common_exit() return void
	serial: max310x: Make max310x_remove() return void
	serial: sc16is7xx: Make sc16is7xx_remove() return void

Please don't apply these (unless you also fix the trivial problems in
them). I will prepare a v2 soon.

Best regards and sorry for the inconvenience,
Uwe
