Struct bd6107_platform_data refers to a platform device within

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")

Thanks for going through the backlight patches.



Daniel.

PS Please don't treat this as an Acked-by, if you want to land this
patchset via a single tree please coordinate with Lee Jones!

I'd like to merge them via drm-misc-next together with the rest of the patchset. It's not DRM, but fbdev patches often go through that tree quite often.

Best regards
Thomas
