Bug#721871: i915 backlight quirk needed for Lenovo Yoga 11s



Package: src:linux
Version: 3.10.5-1
Severity: normal

The Lenovo Yoga 11s laptop boots to a black screen (backlight off)
when i915 loads. This is due to the common backlight control inversion
problem, and can be worked around with i915.invert_brightness=1

This should be enough information to add an entry for this laptop to the
intel_quirks table:

This affects both the kernel I'm running and the one in stable too.
