Marc Zyngier 94967b55eb genirq/debugfs: Reinstate full OF path for domain name
On a DT based system, we use the of_node full name to name the
corresponding irq domain. We expect that name to be unique, so so that
domains with the same base name won't clash (this happens on multi-node
topologies, for example).

Since a7e4cfb0a7 ("of/fdt: only store the device node basename in
full_name"), of_node_full_name() lies and only returns the basename. This
breaks the above requirement, and we end-up with only a subset of the
domains in /sys/kernel/debug/irq/domains.

Let's reinstate the feature by using the fancy new %pOF format specifier,
which happens to do the right thing.

Fixes: a7e4cfb0a7 ("of/fdt: only store the device node basename in full_name")

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.
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.
