Because we are using platform_device_probe() to register the driver
we do not need to assign driver's probe method. We also can mark
ske_keypad_probe(), together with ske_keypad_chip_init(), as __init
instead of __devinit.

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in input dir
are actually calling out for <module.h> explicitly in advance.
