Yazen Ghannam 83be4bee57 ACPI: PRM: Add acpi_prm_handler_available()
Add a helper function to check if a PRM handler/module is present.

This can be used during init time by code that depends on a particular
handler. If the handler is not present, then the code does not need to
be loaded.

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.
