[PATCH] drm/amd/display: Add fast path for cursor plane updates

[Grodzovsky, Andrey]

Not an expert on Freesync so maybe stupid question but from he comment 
looks like this pipe locking is only for the sake of Freesync mode there 
- why is it then called unconditionally w/o checking if you even run in 
Freesync mode ?
