Merge tag 'mmc-v5.10-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC fixes from Ulf Hansson:
 "A couple of MMC fixes:

  MMC core:
   - Fixup condition for CMD13 polling for RPMB requests

  MMC host:
   - mtk-sd: Fix system suspend/resume support for CQHCI
   - mtd-sd: Extend SDIO IRQ fix to more variants
   - sdhci-of-arasan: Fix clock registration error for Keem Bay SOC
   - tmio: Bring HW to a sane state after a power off"

* tag 'mmc-v5.10-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc:
  mmc: mediatek: mark PM functions as __maybe_unused
  mmc: block: Fixup condition for CMD13 polling for RPMB requests
  mmc: tmio: improve bringing HW to a sane state with MMC_POWER_OFF
  mmc: sdhci-of-arasan: Fix clock registration error for Keem Bay SOC
  mmc: mediatek: Extend recheck_sdio_irq fix to more variants
