drm_hwcomposer: Fix HwcLayer::GetReleaseFences() GetReleaseFences() should return release fence for the prior buffer (not for the one assigned to layer at the moment of GetReleaseFences call). Once not provided, old front buffer can be damaged before new buffer presented. (Such issues start to appear once we started using non-blocking DRM/KMS commits). Using present (out) fence is a perfect solution, since it is signaled once old buffer replaced with the new one. Signed-off-by: Roman Stratiienko <roman.o.stratiienko@globallogic.com>
