From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently burst is clamping on rate and not burst, the assignment
of burst from the clamping discards the previous assignment of burst.
This looks like a cut-n-paste error from the previous clamping
calculation on ramp. Fix this by replacing ramp with burst.
