Javi Merino d2180e0cf7 [media] v4l: async: make v4l2 coexist with devicetree nodes in a dt overlay
In asds configured with V4L2_ASYNC_MATCH_OF, the v4l2 subdev can be
part of a devicetree overlay, for example:

&media_bridge {
	...
	my_port: port@0 {
		#address-cells = <1>;
		#size-cells = <0>;
		reg = <0>;
		ep: endpoint@0 {
			remote-endpoint = <&camera0>;
		};
	};
};

/ {
	fragment@0 {
		target = <&i2c0>;
		__overlay__ {
			my_cam {
				compatible = "foo,bar";
				port {
					camera0: endpoint {
						remote-endpoint = <&my_port>;
						...
					};
				};
			};
		};
	};
};

Each time the overlay is applied, its of_node pointer will be
different.  We are not interested in matching the pointer, what we
want to match is that the path is the one we are expecting.  Change to
use of_node_cmp() so that we continue matching after the overlay has
been removed and reapplied.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
