Subject: [PATCH AUTOSEL 4.20 055/304] drm/amd/display: fix gamma not being applied correctly
Date: Mon, 28 Jan 2019 10:39:32 -0500 [thread overview]
Message-ID: <20190128154341.47195-55-sashal@kernel.org> (raw)
In-Reply-To: <20190128154341.47195-1-sashal-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>
From: Murton Liu <murton.liu@amd.com>
[ Upstream commit 8ce504b9389be846bcdf512ed5be8f661b3bf097 ]
[why]
Gamma was always being set as identity on SDR monitor,
leading to no changes in gamma. This caused nightlight to
not apply correctly.
[how]
Added a default gamma structure to compare against
in the sdr case.
