Merge tag 'mmc-fixes-for-3.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
Pull MMC fixes from Chris Ball:
- Build fix for omap_hsmmc with OF against 3.4-rc1.
- Fix CONFIG_MMC_UNSAFE_RESUME semantics regression against 3.3, which
broke hotplug card detection when UNSAFE_RESUME is set.
- Fix a race condition in omap_hsmmc with runtime PM.
- Fix two libertas SDIO-powered-resume regressions.
- Small fixes for discard/sanitize, dw_mmc, cd-gpio and esdhc-imx.
