snd_soc_dai_digital_mute() will return -ENOTSUPP if driver doesn't support mute. In hdmi-codec case, hdmi_codec_digital_mute() will be used for it, and each driver has .digital_mute() callback. hdmi_codec_digital_mute() want to return -ENOTSUPP to follow it.

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.
