Subject: [PATCH 1/2] gpio: msm: Fix irq mask/unmask by writing bits instead of numbers
Date: Tue, 10 Dec 2013 15:19:03 -0800 [thread overview]
Message-ID: <1386717544-478-1-git-send-email-sboyd@codeaurora.org> (raw)
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.
