Subject[PATCH] arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro
Date
From: Suravee Suthikulpanit <Suravee.Suthikulpanit@amd.com>

Arm64 does not define dma_get_required_mask() function.
Therefore, it should not define the ARCH_HAS_DMA_GET_REQUIRED_MASK.
This causes build errors in some device drivers (e.g. mpt2sas)
