Umang Jain 9ef1203fc7 ALSA: pcm: Harden the spk_alloc assumption check
If the parsed ELD has spk_alloc=0, it currently assigns the parsed ELD
spk_alloc to 0xffff. However, we should also check if there is at least
one SAD (Short audio descriptor) to enforce the assumption, as ELD
without any sad_count, is usually considered invalid for e.g. in
commit ce9778b7a0272("ALSA: hda/hdmi: Consider ELD is invalid when no
SAD is present").

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 reStructuredText 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.
