Pull MMC and MEMSTICK updates from Ulf Hansson:
 "MMC core:
   - Update maintainer and URL for the mmc-utils
   - Set default label for slot-gpio in case of no con-id
   - Convert MMC card DT bindings to a schema
   - Add optional host specific tuning support for eMMC HS400
   - Add error handling of add_disk()

  MMC host:
   - mtk-sd: Add host specific tuning support for eMMC HS400
   - mtk-sd: Make DMA handling more robust
   - dw_mmc: Prevent hangs for some data writes
   - dw_mmc: Move away from using the ->init_card() callback
   - mxs-mmc: Manage the regulator in the error path and in ->remove()
   - sdhci-cadence: Add support for the Microchip MPFS variant
   - sdhci-esdhc-imx: Add support for the NXP S32G2 variant
   - sdhci-of-arasan: Add support for the Intel Thunder Bay variant
   - sdhci-omap: Prepare to support more SoCs
   - sdhci-omap: Add support for omap3 and omap4 variants
   - sdhci-omap: Add support for power management
   - sdhci-omap: Add support for system wakeups
   - sdhci-msm: Add support for the msm8226 variant
   - sdhci-sprd: Verify that the DLL locks according to spec

  MEMSTICK:
   - Add error handling of add_disk()
   - A couple of small fixes and improvements"
