Interrupts which have no action and chained interrupts can be
ignored due to the following reasons (as per tglx's comment):
1) Interrupts which have no action are completely uninteresting as
there is no real information attached.
2) Chained interrupts do not have a count at all.
So there is no point to evaluate the number of accounted interrupts before
checking for non-requested or chained interrupts.
Remove the any_count logic and simply check whether the interrupt
descriptor has the kstat_irqs member populated.

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.
