Merge branch 'next-spi' of git://git.secretlab.ca/git/linux-2.6
* 'next-spi' of git://git.secretlab.ca/git/linux-2.6:
spi/amba_pl022: Fix probe and remove hook section annotations.
spi/mpc5121: change annotations for probe and remove functions
spi/bitbang: reinitialize transfer parameters for every message
spi/spi-gpio: add support for controllers without MISO or MOSI pin
spi/bitbang: add support for SPI_MASTER_NO_{TX, RX} modes
SPI100k: Fix 8-bit and RX-only transfers
spi/mmc_spi: mmc_spi adaptations for SPI bus locking API
spi/mmc_spi: SPI bus locking API, using mutex
Fix trivial conflict in drivers/spi/mpc512x_psc_spi.c due to 'struct
of_device' => 'struct platform_device' rename and __init/__exit to
__devinit/__devexit fix.
