Merge tag 'mmc-v4.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc 

Pull MMC fixes from Ulf Hansson:
 "MMC core:

   - kmalloc sdio scratch buffer to make it DMA-friendly

  MMC host:

   - dw_mmc: Fix behaviour for SDIO IRQs when runtime PM is used

   - sdhci-esdhc-imx: Correct pad I/O drive strength for UHS-DDR50
     cards"

* tag 'mmc-v4.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc:
  mmc: sdhci-esdhc-imx: increase the pad I/O drive strength for DDR50 card
  mmc: dw_mmc: Don't allow Runtime PM for SDIO cards
