[PATCH 1/2] gpio: msm: Fix irq mask/unmask by writing bits instead of numbers

From: Stephen Boyd <hidden>
Date: 2013-12-10 23:19:11
Also in: linux-arm-msm, linux-gpio, lkml
Subsystem: gpio subsystem, the rest · Maintainers: Linus Walleij, Bartosz Golaszewski, Linus Torvalds

We should be writing bits here but instead we're writing the
numbers that correspond to the bits we want to write. Fix it by
wrapping the numbers in the BIT() macro. This fixes gpios acting
as interrupts.
