Hello Mr. Albert Zhang, 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. As you are the author of this driver, so I would like to request you if you could help to test this patch or provide us the contact points of individuals who could support to get this patch tested? Thank you!
