+Subject: backlight/bd6107: Compare against struct fb_info.device
+
+From: Thomas Zimmermann <tzimmermann@suse.de>
+
+commit 992bdddaabfba19bdc77c1c7a4977b2aa41ec891 upstream.
+
+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.
+
+v2:
+       * move renames into separate patch (Javier, Sam, Michael)
+
+Fixes: 67b43e590415 ("backlight: Add ROHM BD6107 backlight driver")
