Previously for cyclic dma mode, once sdma fails sdma channel status will be set to DMA_ERROR, unless the transfer is prepared again, sdmac status will always be kept to DMA_ERROR, even the transfer for following buffers is successful. This patch updates sdmac status to the status of current buffer descriptor. Signed-off-by: Jiada Wang <jiada_wang@mentor.com> --- drivers/dma/imx-sdma.c | 2 ++ 1 file changed, 2 insertions(+)
