+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.
