    Subject[PATCH 3.13 157/198] arm64/dma: Removing ARCH_HAS_DMA_GET_REQUIRED_MASK macro
    Date
    3.13.11.5 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Suravee Suthikulpanit <Suravee.Suthikulpanit@amd.com>

    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)
