Not directly related to this patch, but this is slightly annoying:

cdns-mhdp8546 a000000.dp-bridge: invalid resource
cdns-mhdp8546 a000000.dp-bridge: Failed to get SAPB memory resource, HDCP not supported

The first one is an error print and the second is a warning. I think a dev_info about HDCP not supported would be enough.
