drm/sun4i: dsi: Prevent underflow when computing packet sizes 2022-08-15T07:09:49+00:00 Samuel Holland samuel@sholland.org 2022-08-12T03:16:23+00:00 82a1356a933d8443139f8886f11b63c974a09a67 Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could underflow and wrap around to near the maximal u16 value. Fix this by using signed subtraction. The call to max() will correctly handle any negative numbers that are produced. Apply the same fix to the other timings, even though those subtractions are less likely to underflow.
