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 fixes who have come in near or during the merge window: - Removal of a VLA usage in Marvell mpp platform code - Enable some IPMI options for ARM64 servers by default, helps testing - Enable PREEMPT on 32-bit ARMv7 defconfig - Minor fix for stm32 DT (removal of an unused DMA property) - Bugfix for TI OMAP1-based ams-delta (-EINVAL -> IRQ_NOTCONNECTED)" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: dts: stm32: update HASH1 dmas property on stm32mp157c ARM: orion: avoid VLA in orion_mpp_conf ARM: defconfig: Update multi_v7 to use PREEMPT arm64: defconfig: Enable some IPMI configs soc: ti: QMSS: Fix usage of irq_set_affinity_hint ARM: OMAP1: ams-delta: Fix impossible .irq < 0
