Kai-Heng Feng 336322e8b5 ALSA: hda/realtek - Fix S3 pop noise on Dell Wyse
[ Upstream commit 52e4e36807 ]

Commit 317d931392 ("ALSA: hda/realtek - Set default power save node to
0") makes the ALC225 have pop noise on S3 resume and cold boot.

The previous fix enable power save node universally for ALC225, however
it makes some ALC225 systems unable to produce any sound.

So let's only enable power save node for the affected Dell Wyse
platform.

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
