Merge tag 'mmc-v5.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc 

Pull MMC fixes from Ulf Hansson:
 "A couple of MMC fixes intended for v5.0-rc7.

  MMC core:
   - Fix deadlock bug for block I/O requests

  MMC host:
   - sunxi: Disable broken HS-DDR mode for H5 by default
   - sunxi: Avoid unsupported speed modes declared via DT
   - meson-gx: Restore interrupt name"

* tag 'mmc-v5.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc:
  mmc: meson-gx: fix interrupt name
  mmc: block: handle complete_work on separate workqueue
  mmc: sunxi: Filter out unsupported modes declared in the device tree
  mmc: sunxi: Disable HS-DDR mode for H5 eMMC controller by default
