+Subject: [PATCH] Platform: fix samsung-laptop DMI identification for
+ N150/N210/220/N230
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some samsung latop of the N150/N2{10,20,30} serie are badly detected by the samsung-laptop platform driver, see bug # 36082.
+It appears that N230 identifies itself as N150/N210/N220/N230 whereas the other identify themselves as N150/N210/220.
+This patch attemtp fix #36082 allowing correct identification for all the said netbook model.
