From 3632ff141eb7ffb2f9555601411aeedab69cacff Mon Sep 17 00:00:00 2001
From: Matthias Kaehlcke <mka@chromium.org>
Date: Wed, 7 Feb 2018 11:49:28 -0800
Subject: [PATCH 3523/4131] drm/amd/display: Remove extra pairs of parentheses
in dce_calcs.c
The double parentheses are not needed. Removing them fixes multiple
warnings like this when building with clang:
drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dce_calcs.c:617:42:
error: equality comparison with extraneous parentheses
[-Werror,-Wparentheses-equality]
if ((data->graphics_micro_tile_mode == bw_def_rotated_micro_tiling)) {
