From d73c5624eb62a1b88f18296d53ee6b9b2bf0e773 Mon Sep 17 00:00:00 2001 From: Harry Wentland Date: Mon, 2 Oct 2017 15:27:26 -0400 Subject: [PATCH 2543/4131] drm/amd/display: Ignore wrong tautological warning Some of our HW calcs functions compares a var against itself to check for NaN. Gcc isn't fond of it and wrongfully warns about a tautological comparison. Disable this check for dcn_calcs_math.c.
