Subject: [PATCH] drm/vc4: kms: Move clock request to our HVS state
|
|
|
|
Our current clock request has been stored so far on the main HVS
|
|
structure, but even though we shouldn't have two commits in parallel and
|
|
it shouldn't cause any functional change, the request itself is linked
|
|
to a given HVS state.
|
|
|
|
Move the request there to make a bit more sense.
