Currently the snd_compr.lock mutex isn't initialized in the API functions although the lock is used many places in other code in compress offload API. It's because the object was expected to be initialized via snd_compress_register(), but this was never used by ASoC, which is the only user. Instead, ASoC initializes the mutex by itself, and this is error-prone. This patch moves the mutex initialization into the more appropriate place, snd_compress_new(), for avoiding the missing init.

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.
