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

From: Alexander Stein
Date: Fri Feb 04 2022 - 07:15:51 EST


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.
