Johan Hovold f394aa2e42 ASoC: codecs: wsa883x: fix unnecessary initialisation 
commit 49aadf830e upstream.

The soundwire update_status() callback may be called multiple times with
the same ATTACHED status but initialisation should only be done when
transitioning from UNATTACHED to ATTACHED.

This avoids repeated initialisation of the codecs during boot of
machines like the Lenovo ThinkPad X13s:

README 

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 reStructuredText 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.
