Takashi Iwai 4b536c1ec8 ALSA: hda: Avoid spurious unsol event handling during S3/S4 
commit 5ff9dde42e8c72ed8102eb8cb62e03f9dc2103ab upstream.

When HD-audio bus receives unsolicited events during its system
suspend/resume (S3 and S4) phase, the controller driver may still try
to process events although the codec chips are already (or yet)
powered down.  This might screw up the codec communication, resulting
in CORB/RIRB errors.  Such events should be rather skipped, as the
codec chip status such as the jack status will be fully refreshed at
the system resume time.

Since we're tracking the system suspend/resume state in codec
power.power_state field, let's add the check in the common unsol event
handler entry point to filter out such events.

README 

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.
