The fix for the `pp_od_clk_voltage` interface was actually quite simple,
and the bug was limited to that function. The patch just messed up the
return value (which was supposed to be the # of bytes consumed). It was
just returning 0 on success, which caused the userspace client to keep
on trying to send the data.

I suck at email lists, and don't know how to link it here, but I
submitted a patch just now to repair it, if that's the only blocker on this.

Thanks for the work guys,
Matt
