Hi Brian:

Agree, a drm UPAI might be the best & right way for this.

I can raise a new thread/topic to discuss the "HOW TO", maybe after the
Chinese national day.

LAST:
what do you think about this patch:
- Just drop it, waiting for the new uapi
- or keep it, and replace it once new uapi is ready.

Thanks
James
