Bug description:
  Please apply the fix for #1872569 first, then apply this patch.

  [Impact]
  The fix for #1872569 introduces a regression, the driver access a
  NULL pointer on the machiens without Intel hdmi audio codec.

  [Fix]
  pick a fixing patch from alsa/asoc repo, the patch doesn't assume
  the first rtd is for hda codec, it will look for that rtd through
  strstr()

  [Test Case]
  Boot the kenrel on those 2 Dell and 2 Lenovo machines which uses
  this driver, the audio could work. disable the intel hdmi audio codec
  through bios, the analogue audio still works

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