Comment (by JordanCrouse):

 Mea culpa maximus.  I should have never architected the backlight stuff as
 two drivers.  Probably, whats happening here is that the backlight driver
 is coming up at or around the same time as the DCON driver, so the
 dcon_get_backlight() function is returning 0s.

 I am attaching a patch that I have that consolidates the backlight code
 into the DCON driver so that it all comes up at once.  I haven't pushed it
 yet to avoid breaking the build so close to the release, but since this is
 high priority pain, I think we should consider it, assuming it gets the OK
 from the kernel folks.
