[media] V4L: soc-camera: a missing mediabus code -> fourcc translation is not critical
soc_mbus_get_fmtdesc() returning NULL means only, that no standard mediabus code -> fourcc conversion is known, this shouldn't be treated as an error by drivers. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
