AD HD-audio codec driver has a few code lines invoking snd_get_num_conns() and using its return value as the array index without checking. This is basically safe in all those places; at the second and later calls snd_get_num_conns() returns the value cached from the first invocation, hence the value is always consistent. However, it looks a bit confusing as if a lack of the proper check. This patch introduces a new field num_smux_conns in ad198x_spec for simplifying the code. Now we store and refer to the value more locally without invoking the extra function at each time.

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.
