Takashi Iwai 10df962300 ALSA: hda/hdmi: Don't skip notification handling during PM operation 
[ Upstream commit 5226c7b978 ]

The HDMI driver skips the notification handling from the graphics
driver when the codec driver is being in the PM operation.  This
behavior was introduced by the commit eb399d3c99 ("ALSA: hda - Skip
ELD notification during PM process").  This skip may cause a problem,
as we may miss the ELD update when the connection/disconnection
happens right at the runtime-PM operation of the audio codec.

Although this workaround was valid at that time, it's no longer true;
the fix was required just because the ELD update procedure needed to
wake up the audio codec, which had lead to a runtime-resume during a
runtime-suspend.  Meanwhile, the ELD update procedure doesn't need a
codec wake up any longer since the commit 788d441a16 ("ALSA: hda -
Use component ops for i915 HDMI/DP audio jack handling"); i.e. there
is no much reason for skipping the notification.

Let's drop those checks for addressing the missing notification.

Fixes: 788d441a16 ("ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling")

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.
