Subject: [PATCH] drm/vc4: Correct logic on stopping an HVS channel
|
|
|
|
When factoring out __vc4_hvs_stop_channel, the logic got inverted from
|
|
if (condition)
|
|
// stop channel
|
|
to
|
|
if (condition)
|
|
goto out
|
|
//stop channel
|
|
out:
|
|
and also changed the exact register writes used to stop the channel.
|
|
|
|
Correct the logic so that the channel is actually stopped, and revert
|
|
to the original register writes.
|
|
|
|
