    Subject[RFC PATCH 1/3] ARM: dma-mapping: update comment about handling dma_ops when detaching from IOMMU
    Date
    Update the comment because we don't set the pointer to NULL anymore.
    Also use the correct pointer name 'dma_ops' instead of 'dma_map_ops'.

    Fixes: 1874619a7df4 ("ARM: dma-mapping: Set proper DMA ops in arm_iommu_detach_device()")
