Subject: [PATCH 0709/1085] drm/vc4: Drop WARN for HVS FIFOs not being empty
|
||
|
|
|
||
|
|
The reset condition for the EMPTY flag in DISPSTATx is 0,
|
||
|
|
so seeing as we've just reset the pipeline there is no
|
||
|
|
guarantee that the flag will denote empty if it hasn't been
|
||
|
|
enabled.
|
||
|
|
|
||
|
|
Drop the WARN.
|
||
