From a00a5feb1e96ff55c24131472db53dc56cc7570b Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 19 Jul 2020 10:07:40 +0200 Subject: [PATCH] backlight: jornada720_bl: Introduce backlight_is_blank() Use the backlight_is_blank() helper to simplify the code a bit. The jornada720_bl driver distinguish between backlight off and brightness set to 0. Thus this driver turn off backlight only when backlight_is_blank() returns true.
