Smatch reports the following error: drivers/usb/cdns3/cdns3-plat.c:113 cdns3_plat_probe() warn: platform_get_irq() does not return zero From the document, platform_get_irq_byname_optional only returns non-zero value, and negative value on failure. Fix this by removing the zero value checking.

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.
