Subject: [PATCH v9 1/4] media: rkvdec: h264: Limit minimum profile to
 constrained baseline

From: Sebastian Fricke <sebastian.fricke@...labora.com>

Neither the hardware nor the kernel API support FMO/ASO features
required by the full baseline profile. Therefore limit the minimum
profile to the constrained baseline profile explicitly.
