Current code retrieving platform devices MSI devID in the GIC ITS MSI parent helpers suffers from some minor issues: - It leaks a struct device_node reference - It is duplicated between GICv3 and GICv5 for no good reason - It does not use the OF phandle iterator code that simplifies the msi-parent property parsing Consolidate GIC v3 and v5 deviceID retrieval in a function that addresses the full set of issues in one go by merging GIC v3 and v5 code and converting the msi-parent parsing loop to the more modern OF phandle iterator API, fixing the struct device_node reference leak in the process.

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.
