From 403dc5e8aab7b3d18a625e516698ea49d2be432e Mon Sep 17 00:00:00 2001 From: Harry Wentland Date: Tue, 10 Apr 2018 16:06:34 -0400 Subject: [PATCH] drm/amd/display: Use int for calculating vline start We are not sure these calculations will never need negative numbers. Use signed integers and warn and cap at 0 if this ever happens.
