Merge tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull non-critical ARM SoC bug fixes from Arnd Bergmann: "Bug fixes that did not make it into v3.8, mostly because they were not considered important enough, and in some cases because bugs only show up in combination with other patches destined for 3.9. This includes a few larger patches for GPIO on the Marvell PXA platform and a lot of Samsung specific bug fixes, as well as a series from Arnd to fix older build warnings." * tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (54 commits) ARM: SPEAr13xx: Enable CONFIG_ARCH_HAS_CPUFREQ ARM: imx: MACH_MX31ADS_WM1133_EV1 needs REGULATOR_WM8350 scripts/sortextable: silence script output ARM: s3c: i2c: add platform_device forward declaration ARM: mvebu: allow selecting mvebu without Armada XP ARM: pick Versatile by default for !MMU ARM: integrator: fix build with INTEGRATOR_AP off ARM: integrator/versatile: fix NOMMU warnings ARM: sa1100: don't warn about mach/ide.h ARM: shmobile: fix defconfig warning on CONFIG_USB ARM: w90x900: fix legacy assembly syntax ARM: samsung: fix assembly syntax for new gas ARM: disable virt_to_bus/virt_to_bus almost everywhere ARM: dts: Correct pin configuration of SD 4 for exynos4x12-pinctrl ARM: SAMSUNG: Silence empty switch warning in fimc-core.h ARM: SAMSUNG: Silence empty switch warning in sdhci.h ARM: msm: proc_comm_boot_wait should not be __init arm: vt8500: Update MAINTAINERS entry for arch-vt8500 ARM: integrator: ensure ap_syscon_base is initialised when !CONFIG_MMU ARM: S5PV210: Fix early uart output in fifo mode ...
