Quoting Mansur Alisha Shaik (2020-09-23 23:51:06)
> As per current implementation, video driver is unvoting "videom-mem" path
> for last video session during vdec_session_release().
> While video playback when we try to suspend device, we see video clock
> warnings since votes are already removed during vdec_session_release().
> 
> corrected this by putting dummy vote on "video-mem" after last video
> session release and unvoting it during suspend.
