Vinod, Dan,

I've sent the below two patches about three weeks ago, and they haven't
received any comments. They are relatively simple, so would it be
possible to queue them for 3.12 ?

Jason, Andrew, Gregory, as the Marvell EBU maintainers, it would be
great if you could give your Acked-by and/or Tested-by on those patches.

Thanks!

Thomas
