2011-11-11platform: samsung_laptop: fix samsung brightness min/max calculationsJason Stubbs
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.

2011-08-05eeepc-wmi: Add support for T101MT Home/Express Gate keySeth Forshee
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.
