[PATCH] DMA: add cpu_relax() to busy-loop in dma_sync_wait()

From: Bartlomiej Zolnierkiewicz Subject: [PATCH] DMA: add cpu_relax() to busy-loop in dma_sync_wait() Removal of the busy-loop from dma_sync_wait() is not a trivial task so just add cpu_relax() to the loop for now. Cc: Vinod Koul Cc: Dan Williams Cc: Tomasz Figa Signed-off-by: Bartlomiej
