Merge tag 'mmc-v4.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc 

Pull MMC fixes from Ulf Hansson:
 "MMC core:
   - Fix mmc card initialization for hosts not supporting HW busy
     detection
   - Fix mmc_test for sending commands during non-blocking write

  MMC host:
   - mxs: Avoid using an uninitialized
   - sdhci: Restore enhanced strobe setting during runtime resume
   - sdhci: Fix a couple of reset related issues
   - dw_mmc: Fix a reset controller issue"
