  pulseaudio print lots of error when selecting unavailable profile

Status in pulseaudio package in Ubuntu:

Status in pulseaudio source package in Xenial:
  Fix Committed

Bug description:
  SRU Document:


  A HDMI audio device usually has several output ports, each port
  represents a profile in pulseaudio, without this patch, the puseaudio
  always choose the first profile no matter it is active or not.

  [Test Case]

  connect each port of HDMI device, and check if the profile of that
  port is active or not.

  [Regression Potential]

  The patch will check all ports under each profile, if a profile only
  contains unavailable ports, this profile will be set to unavailable as
  well. Without this patch, all profiles are always available, then if a
  profile includes a unusable hdmi-output, and pulseaudio select this
  profile to be active (since its priority is the highest), the kernel
  audio driver will crash.

  I think this patch will not introduce regression:
  1) It is a correct logic to set a profile to be unavailable if it only 
contains unavailable ports.
  2) pulseaudio-artful and pulseaudio-bionic already include this patch, they 
work very well
  3) I tested this patch on 1 lenovo laptop, 1 lenovo desktop, 1 dell laptop 
and 1 dell desktop, all worked well as before
  4) tested this patch on two dell machines (LOAD5-DVT2-A2 and Dawson-JC-C 
without analogue audio) which have unusable hdmi-output profile on them, the 
kernel driver did not crash anymore and audio function worked very well.

  [Other Info]

  Only pulseaudio-xenial has this problem.

  we need to backport this commit to pulseaudio-xenial.


  After printing out the error logs, the kernel crashes and system
