== SRU Justification ==

Impact: On Samsung NF310 and other models, backlight adjustments do not
work properly. The ACPI backlight interface doesn't work at all. The
samsung-laptop driver sort of works, but the backlight can only be set
to brightness levels 0, 1, and 8.

Fix: Upstream cherry pick for samsung-laptop to quirk brightness
adjustments for affected models.

Test Case: I've verified this personally on the NF310. Also verified to
help on the N220P on LP #810093, although an additional patch is
required to fully fix the issues on that machine.
