    dma-debug: skip debug_dma_assert_idle() when disabled · c9d120b0
    Haggai Eran authored
    If dma-debug is disabled due to a memory error, DMA unmaps do not affect
    the dma_active_cacheline radix tree anymore, and debug_dma_assert_idle()
    can print false warnings.
    
    Disable debug_dma_assert_idle() when dma_debug_disabled() is true.
