Subject: media: platform: Use dev_err_probe instead of dev_err Author: Wang Ming <[email protected]> Date: Wed Jul 26 19:51:58 2023 +0800 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.
