Pull ARM SoC fixes from Arnd Bergmann:
"There are three more fixes for this week:
- The Windows-on-ARM laptops require a workaround to prevent crashing
at boot from ACPI
- The Renesas 'draak' board needs one bugfix for the backlight
regulator
- Also for Renesas, the 'hihope' board accidentally had its eMMC
turned off in the 5.3 merge window"
