During bcm_vk_probe(), pci_alloc_irq_vectors() is called passing the number of IRQ vectors as 1, but, later, check how many IRQ vectors it got, and fails if it is smaller than VK_MSIX_IRQ_MIN_REQ. The most appropriated way to do it is setting the 'min_vecs' param as VK_MSIX_IRQ_MIN_REQ, instead of one. pci_alloc_irq_vectors() should know the requirements when called. The test was done by just loading this module on a machine with a Valkyrie offload engine hardware.

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.
