gpio: msm: Fix irq mask/unmask by writing bits instead of numbers
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. Cc: stable@vger.kernel.org Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
