-Subject: [PATCH] drm/vc4: Allow some more signals to be packed with uniform
- resets.
-
-The intent was to make sure people don't sneak in a small immediate or
-something to change the interpretation of the uniform update args, but
-these signals are just fine.
-
-Fixes a validation failure in the current X server on some Render
-operation.

-(cherry picked from commit 313a61d30761217ce4383018de1cc0d5d503a376)
