This patch just adds the DMI info for the samsung laptop driver to work with
the NC210/NC110. It needs the brightness quirk patch for proper support.

On some Samsung laptops the brightness regulation works slightly different.
All SABI commands except for set_brightness work as expected. The behaviour
of set_brightness is as follows:

- Setting a new brightness will only step one level toward the new brightness
  level. For example, setting a level of 5 when the current level is 2 will
  result in a brightness level of 3.
- A spurious KEY_BRIGHTNESS_UP or KEY_BRIGHTNESS_DOWN event is also generated
  along with the change in brightness.
- Neither of the above two issues occur when changing from/to brightness
  level 0.

This patch adds detection and a non-intrusive workaround for the above issues.

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.

The AMW0 function in acer-wmi works on Lenovo ideapad S205 for control
the wifi hardware state. We also found there have a 0x78 EC register
exposes the state of wifi hardware switch on the machine.

So, add this patch to support Lenovo ideapad S205 wifi hardware switch
in acer-wmi driver.

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.

This key is different than other hotkeys, having seperate scan
codes for press, release, and hold, so it requires some special
filtering. Press and release events are passed on, and hold events
are ignored since sparse-keymap does not support hardware
autorepeat.

Note that "Home" in the context of this button doesn't mean the
same thing as the usual Home key, and it really isn't clear at
all what is meant by "Home". The manufacurer's description of the
button indicates that it should launch some sort of touch screen
settings interface on short press and apply a desktop rotation on
long press.
