Hi, I saw this wasn't included in 2.6.34. From my side is ok, I was without any
topstar notebook for some time, now I got a sample and tested it too, the patch
is ok, It only needs a rediff now with latest 2.6.34-rc2-gitX
I thought it was going to be included without any ack etc., if needed you can add:
Acked-by: Herton Ronaldo Krzesinski <herton@xxxxxxxxxxxxxxx>
and tested-by or signed-off if desired.
The rediffed patch for latest 2.6.34 is below:
