I can't help thinking it would be better to separate this into separate
drivers for each part (backlight, power supply etc), and move them into
the appropriate driver directories (drivers/power/supply,
drivers/video/backlight etc). That way each part would get proper review
from the appropriate maintainers (or at least they should be Cc'd).
Is there a particular reason for it to be a single driver?
Cheers
