[PATCH 4/8] media: imx: Fail conversion if pixel format not supported

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dorota Czaplejewicz <dorota.czaplejewicz@xxxxxxx>

imx_media_find_mbus_format has NULL as a valid return value,
therefore the caller should take it into account.
