backlight: lcd: Replace check_fb with controls_device

2024-09-30T15:49:42Z

Rename check_fb in struct lcd_ops to controls_device. The callback is now independent from fbdev's struct fb_info and tests if an lcd device controls a hardware display device. The new naming and semantics follow similar functionality for backlight devices. v2: - fix typos in commit description (Daniel) Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Thompson Link: https://lore.kernel.org/r/20240906075439.98476-27-tzimmermann@suse.de Signed-off-by: Lee Jones

backlight: platform_lcd: Use lcd power constants

2024-09-30T15:49:42Z

Replace FB_BLANK_ constants with their counterparts from the lcd subsystem. The values are identical, so there's no change in functionality.

This reverts commit 52e842432f36d5b15227d0ee0d2aa3d2bc3cc0b2. The DT support never would have worked because there's no platform_data providing ops. There's not any documented binding for it either.
