Ah yes, I noticed that too, as you see from the review I just sent through. Sorry, I didn't see the above post until after I'd sent the review in. It's no big deal though. > Jonathan, as this series is already long overdue, I suggest the > following course of action: please review these patches anyway and if > you find no other issues, please provide your Reviewed-by etc. as you > normally would.

As per my review comments, I am happy with the patch series so long as the backlight device name reverts to "fujitsu-laptop". Your suggested course of action sounds fine to me. Alternatively, I could quickly and easily add tags to a v4 post if that is seen to be more appropriate by Darren/Andy. I'm easy either way. Regards jonathan
