Subject: [PATCH 1/6] auxdisplay/ht16k33: Replace use of fb_blank with backlight helper
Date: Wed, 13 Mar 2024 16:45:00 +0100	[thread overview]
Message-ID: <20240313154857.12949-2-tzimmermann@suse.de> (raw)
In-Reply-To: <20240313154857.12949-1-tzimmermann@suse.de>

Replace the use of struct backlight_properties.fb_blank with a
call to backlight_get_brightness(). The helper implement the same
logic as the driver's function.
