Comment(by lars):
In 2.6.32/2.6.34 the generic-bl driver was replaced with the pcf50633-bl
driver. Which does basically the same but integrates nicer into the core
pcf50633 driver.
I guess it would be interesting to see the regulator states of the
pcf50633 at the end of suspend. This needs some kernel hacking though
maybe adding a late suspend callback to the regulator driver.
