[ Upstream commit6f194c99f4] When using a NOMAP domain, __irq_resolve_mapping() doesn't store the Linux IRQ number at the address optionally provided by the caller. While this isn't a huge deal (the returned value is guaranteed to the hwirq that was passed as a parameter), let's honour the letter of the API by writing the expected value.

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.
