* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/drzeus/mmc: (68 commits) sdio_uart: Fix SDIO break control to now return success or an error mmc: host driver for Ricoh Bay1Controllers sdio: sdio_io.c Fix sparse warnings sdio: fix the use of hard coded timeout value. mmc: OLPC: update vdd/powerup quirk comment mmc: fix spares errors of sdhci.c mmc: remove multiwrite capability wbsd: fix bad dma_addr_t conversion atmel-mci: Driver for Atmel on-chip MMC controllers mmc: fix sdio_io sparse errors mmc: wbsd.c fix shadowing of 'dma' variable MMC: S3C24XX: Refuse incorrectly aligned transfers MMC: S3C24XX: Add maintainer entry MMC: S3C24XX: Update error debugging. MMC: S3C24XX: Add media presence test to request handling. MMC: S3C24XX: Fix use of msecs where jiffies are needed MMC: S3C24XX: Add MODULE_ALIAS() entries for the platform devices MMC: S3C24XX: Fix s3c2410_dma_request() return code check. MMC: S3C24XX: Allow card-detect on non-IRQ capable pin MMC: S3C24XX: Ensure host->mrq->data is valid ... Manually fixed up bogus executable bits on drivers/mmc/core/sdio_io.c and include/linux/mmc/sdio_func.h when merging.
