Merge tag 'mmc-fixes-for-3.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
MMC fixes for 3.3-rc4:
* The most visible fix here is against a regression introduced in 3.3-rc1
that ran cards in Ultra High Speed mode even when they failed to initialize
in that mode, leading to lower-speed cards failing to mount.
* A lockdep warning introduced in 3.3-rc1 is fixed.
* Various other small driver fixes, most notably for a NULL dereference
when using highmem with dw_mmc.
* tag 'mmc-fixes-for-3.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc:
mmc: dw_mmc: Fix PIO mode with support of highmem
mmc: atmel-mci: save and restore sdioirq when soft reset is performed
mmc: block: Init ro_lock sysfs attr to fix lockdep warnings
mmc: sh_mmcif: fix late delayed work initialisation
mmc: tmio_mmc: fix card eject during IO with DMA
mmc: core: Fix comparison issue in mmc_compare_ext_csds
