Subject: arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro
From: Suravee Suthikulpanit <Suravee.Suthikulpanit@xxxxxxx>
commit f3a183cb422574014538017b5b291a416396f97e upstream.
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)
