[ Upstream commitf16a3bb69a] The driver is written as if platform_get_irq() returns 0 on errors (while actually it returns a negative error code), blithely passing these error codes to request_irq() (which takes *unsigned* IRQ #) -- which fails with -EINVAL. Add the necessary error check to the pre-existing *if* statement forcing the driver into the polling mode...

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.
