From 450afd92d9cb177e0337c9ac26677765aeeff81a Mon Sep 17 00:00:00 2001 From: Stephen Kitt <steve@sk2.org> Date: Tue, 7 Jun 2022 21:23:34 +0200 Subject: [PATCH] fbdev: omapfb: panel-dsi-cm: 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.
