tda998x_configure_audio() is called via some paths where an error return is meaningless, and as a result of moving the audio routing code, this function no longer returns any errors, so let's make it void. We can also make tda998x_write_aif() return void as well. tda998x_configure_audio() also only ever needs to write the current audio settings, so simplify the code in tda998x_audio_hw_params() so that can happen.

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.
