If a 'set_bclk_ratio' call is attempted on a DAI not implementing the method, make it an -ENOSUPP error instead of -EINVAL. Assume the DAI can still be okay with the ratio, just does not care to register a handler. No current in-tree users of snd_soc_dai_set_bclk_ratio seem to inspect the return value, but -ENOSUPP disables an error print from within the common soc_dai_ret return filter. With the new behavior a machine driver can do a blanket 'set_bclk_ratio' on all DAIs on a bus, some of which may care about the ratio, some of which may not.

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.
