+Subject: [PATCH] drm/vc4: Don't wait for vblank on fkms cursor
+ updates.
+
+We don't use the same async update path between fkms and normal kms,
+and the normal kms workaround ended up making us wait.  This became a
+larger problem in rpi-4.14.y, as the USB HID update rate throttling
+got (accidentally?) dropped.
