Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"A few more fixes who have trickled in:
- MMC bus width fixup for some Allwinner platforms
- Fix for NULL deref in ti-aemif when no platform data is passed in
- Fix div by 0 in SCMI code
- Add a missing module alias in a new RPi driver"
* tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
memory: ti-aemif: fix a potential NULL-pointer dereference
firmware: arm_scmi: fix divide by zero when sustained_perf_level is zero
hwmon: rpi: add module alias to raspberrypi-hwmon
arm64: allwinner: dts: h6: fix Pine H64 MMC bus width
