In gicv5_irs_of_init_affinity() a WARN_ON() is triggered if:
1) a phandle in the "cpus" property does not correspond to a valid OF
node
2 a CPU logical id does not exist for a given OF cpu_node
#1 is a firmware bug and should be reported as such but does not warrant a
WARN_ON() backtrace.
#2 is not necessarily an error condition (eg a kernel can be booted with
nr_cpus=X limiting the number of cores artificially) and therefore there
is no reason to clutter the kernel log with WARN_ON() output when the
condition is hit.
Rework the IRS affinity parsing code to remove undue WARN_ON()s thus
making it less noisy.

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.
