   4 Subject: Input: i8042 - add Lenovo LaVie Z to the i8042 reset list

   8 commit 384cf4285b34e08917e3e66603382f2b0c4f6e1b upstream.
   9
  10 The Lenovo LaVie Z laptop requires i8042 to be reset in order to
  11 consistently detect its Elantech touchpad. The nomux and kbdreset
  12 quirks are not sufficient.
  13
  14 It's possible the other LaVie Z models from NEC require this as well.
