[Anatoly Trosinenko <1380249@xxxxxxxxxxxxxxxxxx>]

I have applied this patch:
https://bugzilla.kernel.org/show_bug.cgi?id=16373#c21 on top of stable
3.17.1 kernel from kernel.org (patch said "Hunk #1 succeeded at 5783
(offset 170 lines)."). I tested it personally on my hardware and this
patch fixed this bug (at least on my hardware).

Title:
  [Lenovo IdeaPad Y550P] Mute LED indication is inverted

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce (on my hardware):
  Boot Ubuntu 14.10.
  Press "Mute" hardware button several times.

  What is expected:
  When mute is on button LED is on, when mute is off button LED is off.

  What really happens:
  Mute button LED state is inverted relatively to what is expected.

  Notes:
  This bug is reproducible also when booted into the root shell of the recovery mode and switching mute state on/off with alsamixer while playing some audio file to control the actual mute state (button press does not mute/unmute sound in this case, but LED switches on/off in respond to alsamixer).
