[Bug 1012365] [NEW] Samsung Series 9 laptop 900X3C not all keys correctly translated

[Jerker Nordh]

Public bug reported:

There isn't a correct translation from scancodes to keycodes in place
for the 900X3C laptop, for more information see
"http://jablonskis.org/2012/linux-and-samsung-series-laptop-9-fn-keys/",
however the codes on that page are not correct for 900X3C.

/lib/udev/keymap -i input/event3 gives the following information

(Fn+F1..F12)

scan code: 0xCE   key code: kpplusminus
scan code: 0x89   key code: brightnessdown
scan code: 0x88   key code: brightnessup
scan code: 0x82   key code: switchvideomode
scan code: 0xF7   key code: f22
scan code: 0xA0   key code: mute
scan code: 0xAE   key code: volumedown
scan code: 0xB0   key code: volumeup
got scan code event 0x97 without a key code event
got scan code event 0x96 without a key code event
scan code: 0xB3   key code: prog3
got scan code event 0xD5 without a key code event

The correct functionality would be:
Fn+F1: "Easy Settings"
Fn+F2: Brightness Down (OK)
Fn+F2: Brightness Up (OK)
Fn+F3: Switch Internal/External monitor
Fn+F4: Touchpad On/off
Fn+F6: Mute (OK)
Fn+F7: Vol Down (OK)
Fn+F8: Vol Up (OK)
Fn+F9: Keyboard backlight down
Fn+F10: Keyboard backlight up
Fn+F11: Silent Mode (toggle performance levels for reduced noise)
Fn+F12: Wireless on/off
