I think we should try to remove the dependency with LCD framework and
Backlight framework, and incorporate those functionality as par of
CDF.
you can refer to my similar patch "Make s6e8ax0 panel driver compliant
with CDF" ( http://comments.gmane.org/gmane.linux.drivers.video-input-infrastructure/59187
) which i had posted couple of weeks back, where I made an attempt to
remove "lcd_ops" dependency.
