Starting with v2024.10 dev_iommu_dma_unmap calls during device removal trigger a NULL pointer dereference since the the iommu device is removed before its user. The sparsely used DM_FLAG_VITAL flag is intended for this dependency. This series adds it to the Apple dart iommu driver and implements the two phased device removal to the EFI loader.
Can we get this two small patches merged? They fix a regression although it worked previously just accidentally. The only drivers using DM_FLAG_VITAL are clk-rcar-gen3.c, rzg2l-cpg.c and apple_dart.c all used on arm SoCs. arch/arm/lib/bootm.c already uses a device_remove call with DM_REMOVE_NON_VITAL so adding it to efi_loader looks reasonable as regression fix.
