Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC bug fixes from Arnd Bergmann:
"Four patches for arm-soc this week:
- Kevin Hilman is no longer reachable under his previous email
address. He submitted the patch earlier, but nobody felt
responsible to pick it up.
- One Tegra fix for an incorect register address in device tree.
- IMX multiplatform support exposes a configuration option that leads
to unbootable kernels on all other machines and that needs to
depend on that platform.
- A nontrivial bug fix for the setup of the mxs video output."
