Existing (irq < 0) condition is always false because adev->irq has unsigned type and contains 0 in case of failed irq_of_parse_and_map(). Up to now all the mapping errors were silently ignored. Seems that repairing this check would be backwards-incompatible and might break the probe() for the implementations without IRQ support. Therefore warn the user instead.

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.
