+Subject: [PATCH 2/2] vo: hwdec: drmprime: add separate hwdecs for v4l2request
+
+With all the machinery in place, we can now add the v4l2request hwdecs with a
+different hw device type, and a different initialisation path. This applies to
+both the drmprime and drmprime_overlay hwdecs.
+
+At the moment, the device initialisation is done in the bare minimum way, but
+it can be extended to take a device path (for example) if that makes sense as
+we better understand what meaningful configuration will be.
