As this is not only related to HDR 10 decoding, there are other places in the code which will require similar change.

This is not a very strong argument. You can't add code that will break very easily whenever somebody touches that array and pinky-promise to fix it some time later, just because you want to get your feature merged faster, this is not drivers/staging.
