commit 78a7539b upstream.

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.
