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:

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
