The code was:
rw = data[7] & 0x04 ? (data[7] & 0x03)-4 : (data[7] & 0x03);
wacom_report_rel(wcombo, REL_WHEEL, -rw);
it is changed to:
rw = (signed)(data[7] & 0x04) - (data[7] & 0x03);
input_report_rel(input, REL_WHEEL, rw);
I guess they should report the same value? I don't have a graphire to test with.

What was going on? I am not sure (I am not kidding :). I guess we
wanted to simplify the logical?
