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")

Can the Backlight patches be applied without the others and visa versa?

Unfortunately not. The rest of the series requires the backlight patches.

Are you OK with the patches going through drm?

Shouldn't be an issue.

Please ensure my Ack is added to each patch, even if you have to RESEND.
