Jim Harris acec09e67d uio/uio_pci_generic: don't fail probe if pdev->irq == NULL
Some userspace drivers and frameworks only poll and do not
require interrupts to be available and enabled on the
PCI device.  So remove the requirement that an IRQ is
assigned.  If an IRQ is not assigned and a userspace
driver tries to read()/write(), the generic uio
framework will just return -EIO.

This allows binding uio_pci_generic to devices which
cannot get an IRQ assigned, such as an NVMe controller
behind Intel Volume Management Device (VMD), since VMD
does not support INTx interrupts.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
