[PATCH v4 07/10] fbdev/sh_mobile_lcdc_fb: Remove struct backlight_ops.check_fb

[Thomas Zimmermann]

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.
