[PATCH 01/30] backlight/bd6107: Compare against struct fb_info.device
Struct bd6107_platform_data refers to a platform device within
the Linux device hierarchy. The test in bd6107_backlight_check_fb()
compares it against the fbdev device in struct fb_info.dev, which
is different. Fix the test by comparing to struct fb_info.device.
Fixes a bug in the backlight driver and prepares fbdev for making
struct fb_info.dev optional.
