------------------------------------------------------
From: Haggai Eran <[email protected]>
Subject: dma-debug: skip debug_dma_assert_idle() when disabled
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.
