Merge tag 'mmc-fixes-for-3.5-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
Pull MMC fixes from Chris Ball:
- Revert a patch that made failing to select power class fatal;
it turns out that it fails non-fatally on Tegra boards.
Regression against 3.5-rc1.
- Add the IRQF_ONESHOT flag to the cd-gpio driver, which turned
into a regression in 3.5-rc1 when IRQF_ONESHOT became required
for threaded IRQs with no handler.

mmc: cd-gpio: pass IRQF_ONESHOT to request_threaded_irq()
mmc: core: Revert "skip card initialization if power class selection fails"
