Pull MMC fixes from Ulf Hansson:
 "Here's quite a few MMC fixes intended for v5.2-rc6. This time it also
  contains fixes for a WiFi driver, which device is attached to the SDIO
  interface. Patches for the WiFi driver have been acked by the
  corresponding maintainers.

  Summary:

  MMC core:
   - Make switch to eMMC HS400 more robust for some controllers
   - Add two SDIO func API to manage re-tuning constraints
   - Prevent processing SDIO IRQs when the card is suspended

  MMC host:
   - sdhi: Disallow broken HS400 for M3-W ES1.2, RZ/G2M and V3H
   - mtk-sd: Fixup support for SDIO IRQs
   - sdhci-pci-o2micro: Fixup support for tuning

  Wireless BRCMFMAC (SDIO):
   - Deal with expected transmission errors related to the idle states
     (handled by the Always-On-Subsystem or AOS) on the SDIO-based WiFi
     on rk3288-veyron-minnie, rk3288-veyron-speedy and
     rk3288-veyron-mickey"
