Recent addition of SoundWire stream state-machine checks in linux-next have shown an existing issue with handling soundwire streams in codec drivers. In general soundwire stream prepare/enable/disable can be called from either codec/machine/controller driver. However calling it in codec driver means that if multiple instances(Left/Right speakers) of the same codec is connected to the same stream then it will endup calling stream prepare/enable/disable more than once. This will mess up the stream state-machine checks in the soundwire core. Moving this stream handling to machine driver would fix this issue and also allow board/platform specfic power sequencing. Changes since v1: - removed false error check while setting sruntime.

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.
