Merge tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6
Pull SPI changes for v3.4 from Grant Likely:
"Mostly a bunch of new drivers and driver bug fixes; but this also
includes a few patches that create a core message queue infrastructure
for the spi subsystem instead of making each driver open code it."
