From 0f6071684a10d524e5085d018e31b6d49e1416f4 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 10 Dec 2013 15:19:03 -0800 Subject: gpio: msm: Fix irq mask/unmask by writing bits instead of numbers commit 4cc629b7a20945ce35628179180329b6bc9e552b upstream. 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.
