Merge tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC Non-critical bug fixes from Olof Johansson: "Simple bug fixes that were not considered important enough for inclusion into 3.7, especially those that arrived late during the merge window. There's also a MAINTAINERS update for the Renesas platforms in here, marking Simon Horman as a maintainer and changing the git url to his tree." * tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: Update ARM/SHMOBILE section of MAINTAINERS ARM: Fix Kconfig symbols typo for LEDS ARM: pxa: add dummy SA1100 rtc clock in pxa25x ARM: pxa: fix pxa25x gpio wakeup setting ARM: OMAP4: PM: fix errata handling when CONFIG_PM=n ARM: cns3xxx: drop unnecessary symbol selection ARM: vexpress: fix ll debug code when building multiplatform ARM: OMAP4: retrigger localtimers after re-enabling gic ARM: OMAP4460: Workaround for ROM bug because of CA9 r2pX GIC control register change.
