Merge tag 'spi-fix-v4.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown:
"A small clutch of driver specific fixes.
The OMAP one is a bit worrying since it seems to be triggered by some
changes in the runtime PM core code and I suspect there's other
drivers across that are going to be using the same pattern outside of
OMAP but nothing seems to be coming up in the testing people are
doing"
