[ Upstream commit 6578ed85c7 ]
User space provides the vector as an unsigned int that is checked
early for validity (vfio_set_irqs_validate_and_prepare()).
A later negative check of the provided vector is not necessary.
Remove the negative check and ensure the type used
for the vector is consistent as an unsigned int.

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.
