Merge tag 'msm-cleanup-for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/cleanup
From David Brown:
Cleanups for MSM for 3.11
These are a handful of cleanups to the MSM tree. The gpio cleanups
get us closer to having proper pinmux and gpio support.
* tag 'msm-cleanup-for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
mfd: ssbi: Use devm_* and simplify code
gpio: msm: Add device tree and irqdomain support for gpio-msm-v2
ARM: msm: Remove gpiomux-v2 and re-organize MSM_GPIOMUX configs
msm: iomap: Remove unused bases and mappings
msm: Remove unused file core.h
ARM: msm: Remove init_irq declaration in machine description
