Thomas Zimmermann 47636d32a0 backlight/lv5207lp: Compare against struct fb_info.device 
commit 1ca8819320 upstream.

Struct lv5207lp_platform_data refers to a platform device within
the Linux device hierarchy. The test in lv5207lp_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.

v2:
	* move renames into separate patch (Javier, Sam, Michael)

Fixes: 82e5c40d88 ("backlight: Add Sanyo LV5207LP backlight driver")
