Since the code flow is little different when PP is enabled, we need to make sure the patch is applied for PP enabled path as well. With the current code, when we boot with the amdgpu driver enabled and loaded, the VCE also automatically remains enabled since bootup. This can be verified from the output of amdgpu_pm_info. It does not matter whether we boot into command line directly or into X, the VCE stays enabled the entire time. This patch addresses the issue and makes sure that VCE is turned on only during playback, and remains disabled otherwise.
