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"
