Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"Nothing controversial, just another batch of fixes:
- Samsung/exynos fixes for more merge window fallout: build errors
and warnings mostly, but also some clock/device setup issues on
exynos4/5
- PXA bug and warning fixes related to gpio and pinmux
- IRQ domain conversion bugfixes for U300 and MSM
- A regulator setup fix for U300"
