Commit2fef64eec2("ASoC: hdmi-codec: Add a prepare hook") added a prepare implementation. Back then the new callback was only integrated with hdmi_codec_i2s_dai_ops (which is used by the I2S input code-path). It was not added to hdmi_codec_spdif_dai_ops (which is used by the SPDIF input code-path). With commitbaf616647f("drm/connector: implement generic HDMI audio helpers") the DRM subsystem has gained a helper framework which can be used by HDMI controller drivers. HDMI controller drivers are often tightly coupled with the hdmi-codec because of the so-called HDMI audio infoframe (which is often managed by the display controller). To allow the new DRM HDMI audio framework to work with the hdmi-codec driver for SPDIF inputs we also need to hook up the prepare callback to hdmi_codec_spdif_dai_ops. Just hooking into the hw_params callback would not be enough as hw_params (is called too early and) doesn't have access to the HDMI audio infoframe contents.

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.
