Subject: [ 001/108] samsung-laptop: make the dmi check less strict
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Corentin Chary <corentincj@...aif.net>
commit 3be324a94df0c3f032178d04549dbfbf6cccb09a upstream.
This enable the driver for everything that look like
a laptop and is from vendor "SAMSUNG ELECTRONICS CO., LTD.".
Note that laptop supported by samsung-q10 seem to have a different
vendor strict.
Also remove every log output until we know that we have a SABI interface
(except if the driver is forced to load, or debug is enabled).
Keeping a whitelist of laptop with a model granularity is something that can't
work without close vendor cooperation (and we don't have that).
