Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM Exynos fixes from Olof Johansson: "Here's a shorter set of fixes for 3.10, all for Samsung Exynos platforms. It also includes a defconfig update so that exynos_defconfig provides a meaningful set of drivers to boot an unmodified kernel on the Samsung ARM-based Chromebooks." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: exynos: defconfig update ARM: SAMSUNG: Add names to fimd0 IRQ resources ARM: EXYNOS: fix software reset logic for EXYNOS5440 SOC ARM: EXYNOS: Fix support of Exynos4210 rev0 SoC ARM: dts: Enabling samsung-usb2phy driver for exynos5250
