Date: Tue, 7 Jun 2022 20:20:24 +0200 From: Stephen Kitt <steve@....org> To: Thierry Reding <thierry.reding@...il.com>, Sam Ravnborg <sam@...nborg.org>, David Airlie <airlied@...ux.ie>, Daniel Vetter <daniel@...ll.ch> Cc: dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org, Stephen Kitt <steve@....org> Subject: [PATCH 1/3] drm/panel: Use backlight helper Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.
