commit 9f51ce0b9e73f83bab2442b36d5e247a81bd3401 upstream.
The return from the call to platform_get_irq() is int, it can be
a negative error code, however this is being assigned to an unsigned
int variable 'irqn', so making 'irqn' an int.
Eliminate the following coccicheck warning:
./drivers/gpio/gpio-mpc8xxx.c:391:5-21: WARNING: Unsigned expression
compared with zero: mpc8xxx_gc -> irqn < 0

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.
