Robin Murphy fc67e6f120 ARM: 8835/1: dma-mapping: Clear DMA ops on teardown ... Installing the appropriate non-IOMMU DMA ops in arm_iommu_detch_device() serves the case where IOMMU-aware drivers choose to control their own mapping but still make DMA API calls, however it also affects the case when the arch code itself tears down the mapping upon driver unbinding, where the ops now get left in place and can inhibit arch_setup_dma_ops() on subsequent re-probe attempts. Fix the latter case by making sure that arch_teardown_dma_ops() cleans up whenever the ops were automatically installed by its counterpart.
