[ Upstream commit 751bec089c4eed486578994abd2c5395f08d0302 ] Iterating over disabled ports results in of_irq_parse_raw() parsing the wrong "interrupt-map" entries, as it takes the status of the node into account. This became apparent after disabling unused PCIe ports in the Apple Silicon device trees instead of deleting them. Switching from for_each_child_of_node_scoped() to for_each_available_child_of_node_scoped() solves this issue.

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.
