The u8 variables ramp_ups and ramp_downs are being compared to less
than zero, this will always be false. Fix this by making the ramp
variables ints.
Addresses-Coverity: ("Unsigned compared against 0")

V2: make u8 vars ints rather than removing the comparison. Thanks once
more to Dan Carpenter for spotting my clearly stupid V1 version and
correcting my mistake.
