This means that existing applications are now suddenly required to always pass the scaling matrix for every buffer. Especially since the commit log says: 'HEVC frames *may* use scaling list feature', indicating that this is an optional feature.

Can you fix this when applying if this is the only issue? I realized that after changing this to false, you also need to document what happens if you do NOT set this control in the request. Does it fall back to default values? It looks like the HEVC spec defines some defaults (if I understand it correctly).

It looks like the HEVC spec defines > some defaults (if I understand it correctly). This control is needed only when V4L2_HEVC_SPS_FLAG_SCALING_LIST_ENABLED is set. If flag is set but control is not provided, then it doesn't really matter if default values or old values of control are used, image will be incorrectly decoded anyway. I think it's more important that buffer is marked with VB2_BUF_STATE_ERROR in such case.
