From 36462ac193088db17823b592cb2c08fff6898b23 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Fri, 6 Sep 2024 09:52:34 +0200 Subject: fbdev: clps711x-fb: Replace check_fb in favor of struct fb_info.lcd_dev Store the lcd device in struct fb_info.lcd_dev. The lcd subsystem can now detect the lcd's fbdev device from this field. This makes the implementation of check_fb in clps711x_lcd_ops obsolete. Remove it.
