If you're going to add parameters to a function like backlight_device_register, you could at least grep the tree and update all the users :-(.
yes, you are right. I just noticed that there are so many users when I sent out that patch. And all these users were disabled when I was testing patch. I'm sorry for that.
To top it off, someone noticed some of the failures and fixed them but nobody thought to fix the drivers in drivers/video/backlight itself and a mac reference seems to have escaped too.
If my memory serves me well, there is a patch for mac in mm. Not sure other drivers in video/backlight. But I should have sent it to some place. Need to check.
I'll send a patch to to Andrew to clean up this mess...
