3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <redacted>

commit 07d1d29ee1e194b932328ad2dc1d40297062ab7f upstream.

Seems it helps some users, but causes issues for other users:
https://bugzilla.redhat.com/show_bug.cgi?id=1089545

So lets drop it for now until we've figured out a better fix.

Fixes: 43d949024425 (ACPI / video: Add use_native_backlight quirks for more systems)
