It's not uncommon for the particular device to support only a subset of HDMI InfoFrames. It's not a big problem for the kernel, since we adopted a model of ignoring the unsupported Infoframes, but it's a bigger problem for the userspace: we end up having files in debugfs which do mot match what is being sent on the wire.
Sort that out, making sure that all interfaces are consistent.
