Thanks Boris.
There is another thing which needs your help.
The change of bf756fb833cb was introduced to fix the bug below:
"some hangs observed on suspending when UVD/VCE still using".

So, I need your help to confirm the last two patches(I sent you) do not affect the fix for the bug above.
Please follow the steps below to verify it:
1. Launch a video playing
2. open another terminal and issue "sudo pm-suspend" command to force suspending
3. verify the system can suspend and resume back correctly without errors or hangs
