Merge branch 'next/fixes-non-critical' into next/drivers
Conflicts: arch/arm/mach-lpc32xx/clock.c arch/arm/mach-pxa/pxa25x.c arch/arm/mach-pxa/pxa27x.c The conflicts with pxa are non-obvious, we have multiple branches adding and removing the same clock settings. According to Haojian Zhuang, removing the sa1100 rtc dummy clock is the correct fix here. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
