Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"This is a batch of fixes for arm-soc platforms, most of it is for OMAP
but there are others too (i.MX, Tegra, ep93xx). Fixes warnings, some
broken platforms and drivers, etc. A bit all over the map really."
There was some concern about commit 68136b10 ("RM: sunxi: Change device
tree naming scheme for sunxi"), but Tony says:
"Looks like that's trivial to fix as needed, no need to rebuild the
branch to fix that AFAIK.
The fix can be done once Olof is available online again.
Linus, I suggest that you go ahead and pull this if there are no other
issues with this branch."
