[PATCH] typo in kernel source (INPUT_TWL4030_PWBUTTON)

[Christoph Egger]

 Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we're checking referential integrity between kernel KConfig
options and in-code Conditional blocks.

	While working on this we detected a spelling error in
drivers/mfd/twl-core.c which can be corrected using the attached
patch.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger
