Takashi Iwai 3140aafb22 ALSA: hda/hdmi - Fix i915 reverse port/pin mapping
The recent fix for Icelake HDMI codec introduced the mapping from pin
NID to the i915 gfx port number.  However, it forgot the reverse
mapping from the port number to the pin NID that is used in the ELD
notifier callback.  As a result, it's processed to a wrong widget and
gives a warning like
  snd_hda_codec_hdmi hdaudioC0D2: HDMI: pin nid 5 not registered

This patch corrects it with a proper reverse mapping function.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
