Subject: [ 003/105] samsung-laptop: make the dmi check less strict (part 2)

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

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

From: Ben Hutchings <ben@...adent.org.uk>

commit 3be324a94df0c3f032178d04549dbfbf6cccb09a upstream.

These are the hunks that I dropped when backporting for 3.2.24,
which are applicable now that we also have commit f34cd9ca
('samsung-laptop: don't handle backlight if handled by acpi/video').
