Krzysztof Kozlowski 180cf2e5f7 maiblox: mediatek: Fix handling of platform_get_irq() error
[ Upstream commit 558e4c36ec9f2722af4fe8ef84dc812bcdb5c43a ]

platform_get_irq() returns -ERRNO on error.  In such case casting to u32
and comparing to 0 would pass the check.

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.
