Merge tag 'spi-v3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi fixes from Mark Brown:
"A smattering of driver specific fixes here, including a bunch for a
long standing common pattern in the error handling paths, and a fix
for an embarrassing thinko in the new devm master registration code"
