Subject: Re: [Linux-fbdev-devel] [PATCH] Proper backlight selection for fbdev
 drivers


The problem is the overlap of the patches 

fbdev-update-after-backlight-argument-change.diff
proper-backlight-selection-forfbdev-drivers.patch

The machine_is change is in the argument change patch. It should be in 
this patch. I can send updates of both patches.
