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
