Kailang Yang 582de98b59 ALSA: hda/realtek - Fix speaker volume control on Lenovo C940
commit f86de9b1c0663b0a3ca2dcddec9aa910ff0fbf2c upstream.

Cannot adjust speaker's volume on Lenovo C940.
Applying the alc298_fixup_speaker_volume function can fix the issue.

[ Additional note: C940 has I2S amp for the speaker and this needs the
  same initialization as Dell machines.
  The patch was slightly modified so that the quirk entry is moved
  next to the corresponding Dell quirk entry. -- tiwai ]

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.
