Subject: [PATCH v6 7/9] drm/i915: Restore brightness level in aux backlight driver
Date: Tue, 9 May 2017 16:40:50 -0700 [thread overview]
Message-ID: <20170509234052.189575-8-puthik@chromium.org> (raw)
In-Reply-To: <20170509234052.189575-1-puthik@chromium.org>
Some panel will default to zero brightness when turning the
panel off and on again. This patch restores last brightness
level back when panel is turning back on.
