Dear Mr. Paul Parsons,
I am Aniroop Mathur from Samsung R&D Institute, India.
I have submitted one patch as below for review to Linux Open Source.
The problem is that we do not have the hardware available with us to
test it and we would like to test it before actually applying it.
If you have the hardware available, could you please help to test this patch?
or could you provide contact points of individuals who could support to test it?
Thank you!
BR,
Aniroop Mathur
