Subject: [PATCH 0/3] ARM: MSM: Consolidate MSM gpiomux for 7X30 and 8X50

This series is based on David Brown's for-next branch
git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm.git for-next

The previous gpio patches left some room for consolidation and required
a few fixes. This patch provides the necessary patches to do that.

Rohit Vaswani (3):
ARM: msm: dts: Fix the gpio register address for msm8960
drivers: gpio: msm: Fix the error condition for reading ngpio
ARM: msm: Consolidate gpiomux for older architectures
