Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Cleanups for the Samsung platforms

Various cleanup changes that the device driver changes are built upon.
Since the samsung cleanups depend on the device tree series, which
depends on the first set of cleanups for tegra.

* tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
