Merge tag 'mmc-v6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc
Pull MMC fixes from Ulf Hansson: "A couple of MMC fixes. This time there is also a fix for the ARM SCMI firmware driver, which has been acked by Sudeep Holla, the maintainer. MMC core: - Terminate infinite loop in SD-UHS voltage switch MMC host: - hsq: Fix kernel crash in the recovery path - moxart: Fix bus width configurations - sdhci: Fix kernel panic for cqe irq ARM_SCMI: - Fixup clock management by reverting 'firmware: arm_scmi: Add clock management to the SCMI power domain'" * tag 'mmc-v6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc: mmc: hsq: Fix data stomping during mmc recovery Revert "firmware: arm_scmi: Add clock management to the SCMI power domain" mmc: core: Terminate infinite loop in SD-UHS voltage switch mmc: moxart: fix 4-bit bus width and remove 8-bit bus width mmc: sdhci: Fix host->cmd is null
