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
