mtk_vpu_probe() calls platform_get_resource(pdev, IORESOURCE_IRQ, ..) to check if IRQ resource exists and later calls platform_get_irq(pdev, ..) to get the actual IRQ. This patch drops an unnecessary call to platform_get_resource() and checks the return value of platform_get_irq(pdev, ..) to make sure the IRQ line is valid.

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.
