Subject: [PATCH v2 1/6] auxdisplay: ht16k33: Replace use of fb_blank with backlight helper
Date: Tue, 19 Mar 2024 10:37:20 +0100	[thread overview]
Message-ID: <20240319093915.31778-2-tzimmermann@suse.de> (raw)
In-Reply-To: <20240319093915.31778-1-tzimmermann@suse.de>

Replace the use of struct backlight_properties.fb_blank with a call
to backlight_get_brightness(). The helper implements similar logic
as the driver's function. It also accounts for BL_CORE_SUSPENDED for
drivers that set BL_CORE_SUSPENDRESUME. Ht16k33 doesn't use this, so
there's no change in behaviour here.
