The commit609f548534("ALSA: hda: hdmi - preserve non-MST PCM routing for Intel platforms") tried to restore the old behavior wrt assignment of the PCM slot for Intel platforms, but this didn't do it right. As found in the later discussion, a positive pipe id on Intel platforms can be passed for single monitor attachment case. This patch reverts the previous attempt and applies a simpler workaround instead. Actually, for Intel platforms, we can handle as if per_pin->dev_id=0, assign the primary slot at the first try. This assures the compatible behavior with the previous versions regarding the slot assignment.

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.
