Subject: [PATCH 02/10] auxdisplay/ht16k33: Remove struct backlight_ops.check_fb
Date: Mon, 12 Feb 2024 17:16:35 +0100	[thread overview]
Message-ID: <20240212162645.5661-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20240212162645.5661-1-tzimmermann@suse.de>

The driver sets struct fb_info.bl_dev to the correct backlight
device. Thus rely on the backlight core code to match backlight
and framebuffer devices, and remove the extra check_fb function
from struct backlight_ops.
