6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Zimmermann <[email protected]>

commit 1ca8819320fd84e7d95b04e7668efc5f9fe9fa5c 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: 82e5c40d88f9 ("backlight: Add Sanyo LV5207LP backlight driver")
