It's a little unclear to me who you intend to take this patch.  In the
To field, you've listed Marc, the MSM maintainers, as well as Russell.
The MSM tree doesn't really make sense, since this is general ARM
code.  Marc would make sense if you depend on an active patch series
he is working on, so he could include it.

I'm guessing you meant it for Russell, though, and the rest of us as
CCs.

Thanks,
David
