Merge tag 'fixes-nc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC non-critical fixes from Olof Johansson:
"Here is a collection of fixes (and some intermixed cleanups) that were
considered less important and thus not included in the later parts of
the 3.9-rc cycle.
It's a bit all over the map, contents wise. A series of ux500 fixes
and cleanups, a bunch of various fixes for OMAP and tegra, and some
for Freescale i.MX and even Qualcomm MSM.
Note that there's also a patch on this branch to globally turn off
-Wmaybe-uninitialized when building with -Os. It's been posted
several times by Arnd and no dissent was raised, but nobody seemed
interested to pick it up. So here it is, as the topmost patch."
