[PATCH v2 7/7] staging: kpc2000: remove SetBackEndControl() function

[Greg Kroah-Hartman]

As this is only called twice, just call writel() like a normal driver
should :)

At the same time, clean up the formatting for the irq handler, as there
is no need to have that be incorrect, it just hurts the eyes...
