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" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: PXA2xx: MFP: fix potential direction bug ARM: PXA2xx: MFP: fix bug with MFP_LPM_KEEP_OUTPUT arm/sa1100: fix sa1100-rtc memory resource ARM: pxa: fix gpio wakeup setting ARM: SAMSUNG: add missing MMC_CAP2_BROKEN_VOLTAGE capability ARM: EXYNOS: Fix compilation error when CONFIG_OF is not defined ARM: EXYNOS: Fix resource on dev-dwmci.c ARM: S3C24XX: Fix build warning for S3C2410_PM ARM: mini2440_defconfig: Fix build error ARM: msm: Fix gic irqdomain support ARM: EXYNOS: Fix incorrect initialization of GIC ARM: EXYNOS: use 'exynos4-sdhci' as device name for sdhci controllers ARM: u300: bump all IRQ numbers by one ARM: ux300: Fix unimplementable regulation constraints
