At present, to add PCM substreams for each of available tx/rx streams, this driver uses a condition based on model-name. This is not enough to support unknown models. In former commits, this driver gains cache of stream formats. For models which support protocol extension, all of available steam formats are cached. For known models, hard-coded stream formats are used to generate the cache. For unknown models, stream formats at current mode of sampling transmission frequency is cached. Anyway, at least, the cached formats are used to expose constrains of PCM substreams for userspace applications. Thus, The cached data can be also used to add PCM substreams themselves, instead of the name-based conditions. This commit obsoletes local frag of force_two_pcms.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
