Add a method to get hold of a protocol, causing it to be initialized and its resource accounting updated, without getting access to its operations and handle. Some protocols, like SCMI SystemPower, do not expose any protocol ops to the kernel OSPM agent but still need to be at least initialized. This helper avoids the need to invoke a full devm_get_protocol() only to get the protocol initialized while throwing away unused the protocol ops and handle.

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.
