Subject: [PATCH v3 09/10] fbdev/ssd1307fb: Remove struct backlight_ops.check_fb
Date: Mon, 4 Mar 2024 17:29:54 +0100 [thread overview]
Message-ID: <20240304163220.19144-10-tzimmermann@suse.de> (raw)
In-Reply-To: <20240304163220.19144-1-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.
