4Subject: [PATCH 001/109] samsung-laptop: make the dmi check less strict
5
6commit 3be324a94df0c3f032178d04549dbfbf6cccb09a upstream.
7
8This enable the driver for everything that look like
9a laptop and is from vendor "SAMSUNG ELECTRONICS CO., LTD.".
10Note that laptop supported by samsung-q10 seem to have a different
11vendor strict.
12
13Also remove every log output until we know that we have a SABI interface
14(except if the driver is forced to load, or debug is enabled).
15
16Keeping a whitelist of laptop with a model granularity is something that can't
17work without close vendor cooperation (and we don't have that).
