drm/amd/display: remove useless if/else
Fix the following coccinelle report: ./drivers/gpu/drm/amd/display/dc/calcs/dce_calcs.c:1367:3-5: WARNING: possible condition with no effect (if == else) Both branches are the same, so remove the if/else altogether. Fixes: 81875979f0b2 ("drm/amd/display: Remove extra pairs of parentheses in dce_calcs.c") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Zou Wei <zou_wei@huawei.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
