commit a7ea19926ffba86f373f6050a106cd162dbb9a78 upstream.
samsung_init() should not return success if not all devices are initialized.
Otherwise, samsung_exit() will dereference sdev NULL pointers and others.

commit bee460be8c691c544e84ed678280ace6153104c6 upstream.
The min_brightness value of the sabi_config is incorrectly used in brightness
calculations. For the config where min_brightness = 1 and max_brightness = 8,
the user visible range should be 0 to 7 with hardware being set in the range
of 1 to 8. What is actually happening is that the user visible range is 0 to
8 with hardware being set in the range of -1 to 7.
This patch fixes the above issue as well as a miscalculation that would occur
in the case of min_brightness > 1.

commit 78a7539b881eb557494a7c810625c0307b27296c 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.

dmi_check_system() walks the table running matching functions until
someone returns non zero or we hit the end.
This patch makes dmi_check_cb to return 1 so dmi_check_system() return
immediately when a match is found.
