Several drivers duplicate same code for getting reference to the root node, matching it against 'struct of_device_id' table and getting out the match data from the table entry. There is a of_machine_compatible_match() wrapper but it takes array of strings, which is not suitable for many drivers since they want the driver data associated with each compatible. Add two wrappers, similar to existing of_device_get_match_data(): 1. of_machine_device_match() doing only matching against 'struct of_device_id' and returning bool. 2. of_machine_get_match_data() doing the matching and returning associated driver data for found compatible.

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.
