  [Lenovo Thinkpad Edge E525] Microphone mute key does not work

Bug description:
  CID: 201108-8258 Lenovo Thinkpad Edge E525

  The microphone mute key does not work on this system (on F4).

  Debugging information:
  1. sudo showkey
  keycode 190 press
  keycode 190 release

  2. xev
  KeyRelease event, serial 40, synthetic NO, window 0x3600001,
      root 0xa6, subw 0x0, time 50938864, (396,75), root:(462,127),
      state 0x10, keycode 198 (keysym 0x0, NoSymbol), same_screen YES,
      XLookupString gives 0 bytes: 
      XFilterEvent returns: False

  KeyRelease event, serial 40, synthetic NO, window 0x3600001,
      root 0xa6, subw 0x0, time 50938864, (396,75), root:(462,127),
      state 0x10, keycode 198 (keysym 0x0, NoSymbol), same_screen YES,
      XLookupString gives 0 bytes: 
      XFilterEvent returns: False

  It's weird that the keycode captured between xev and showkey is
  different.

  Bug 408903 is a similar bug, I open this one since the keycode
  captured here is totally different.
