Subject: drm/i915: Add HP nx9020/SamsungSX20S to ACPI LID quirk list
X-Git-Tag: v2.6.33-rc5~62^2~15

drm/i915: Add HP nx9020/SamsungSX20S to ACPI LID quirk list

The HP comaq nx9020/Samsung SX20S laptop always report that the LID status is
closed and we can't use it reliabily for LVDS detection. So add the two boxes
into the quirk list.
