Change the interface to stop the DMA trace for suspend. Replace the snd_sof_init_trace_ipc() and snd_sof_release_trace() calls with more explicit interface for PM (the sole user for this interface). The new snd_sof_trace_suspend() call takes the target PM state as argument, allowing the trace implementation to decide how to handle the transition. Use this information to release DMA resources only if DSP is suspended and will not remain in D0.

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.
