It is possible that dma_request_chan will return EPROBE_DEFER, which means that dma->xdev->dev is not ready yet. In this case, dev_err(dma->xdev->dev), there will be no output. This patch fixes the bug. Signed-off-by: Wang Ming <machel@vivo.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> |
