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)"
