Merge tag 'mmc-v4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC fixes from Ulf Hansson:
 "Here are some mmc fixes intended for v4.9 rc2.

  This time I have also included a few changes for a memstick driver
  which has a corresponding mmc driver. They use the same USB device as
  parent, hence both needs to play nice with runtime PM, which they
  didn't.

  MMC core:
   - Update MAINTAINERS as the mmc tree moved to kernel.org
   - A few fixes for HS400es mode
   - A few other minor fixes

  MMC host:
   - sdhci: Fix an issue when dealing with stop commands
   - sdhci-pci: Fix a bus power failure issue
   - sdhci-esdhc-imx: Correct two register accesses
   - sdhci-of-arasan: Fix the 1.8V I/O signal switch behaviour
   - rtsx_usb_sdmmc: Fix runtime PM issues

  Other: (Because of no maintainer)
   - memstick: rtsx_usb_ms: Fix runtime PM issues"
