Pull spi fixes from Mark Brown:
"A few driver specific fixes, the biggest one being a fix for the newly
added Qualcomm SPI controller driver to make it not use its internal
chip select due to hardware bugs, replacing it with GPIOs"
* tag 'spi-v3.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
spi: qup: Remove chip select function
spi: qup: Fix order of spi_register_master
