Subject: [PATCH 0599/1085] drm/vc4: Fix dlist debug not resetting the next
 | 
						|
 entry pointer
 | 
						|
 | 
						|
The debug function to display the dlists didn't reset next_entry_start
 | 
						|
when starting each display, so resulting in not stopping the
 | 
						|
list at the correct place.
