Bug description:
  [Impact]
  When users plug a headset into the audio jack on Lenovo x1c7, the
  audio driver can't stay in the rt_suspend state anymore

  [Fix]
  don't let the driver trigger the fake key event

  [Test Case]
  boot the kenrel, enable the dyndbg on the codec driver,
  plug/unplug the headset, check the runime pm status in the dmesg

  [Regression Risk]
  Low, I have tested this patch Lenovo machines, they all worked well.
