The current SCU IPC API has been operating on a single instance and there has been no way to pin the providing module in place when the SCU IPC is in use. This implements a new API that takes the SCU IPC instance as first parameter (NULL means the single instance is being used). The SCU IPC instance can be retrieved by calling new function intel_scu_ipc_dev_get() that take care of pinning the providing module in place as long as intel_scu_ipc_dev_put() is not called. The old API is updated to call the new API and is is left there in the legacy API header to support the existing users that cannot be converted easily. Subsequent patches will convert most of the users over to the new API.

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.
