[PATCH v4 5/5] media: imx: Fail conversion if pixel format not supported

From: Dorota Czaplejewicz <hidden>
Date: 2021-11-04 11:44:49
Also in: linux-media, linux-staging, lkml, phone-devel
Subsystem: media drivers for freescale imx, media input infrastructure (v4l/dvb), staging subsystem, the rest · Maintainers: Steve Longerbeam, Philipp Zabel, Mauro Carvalho Chehab, Greg Kroah-Hartman, Linus Torvalds

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