Subject: [PATCH] drm/vc4: crtc: Move the BO handling out of common
|
||
|
|
page-flip callback
|
||
|
|
|
||
|
|
We'll soon introduce another completion callback source that won't need
|
||
|
|
to use the BO reference counting, so let's move it around to create a
|
||
|
|
function we will be able to share between both callbacks.
