Inochi Amaoto e433110eb5 PCI: vmd: Override irq_startup()/irq_shutdown() in vmd_init_dev_msi_info() 
Since commit 54f45a30c0 ("PCI/MSI: Add startup/shutdown for per
device domains") set callback irq_startup() and irq_shutdown() of
the struct pci_msi[x]_template, __irq_startup() will always invokes
irq_startup() callback instead of irq_enable() callback overridden
in vmd_init_dev_msi_info(). This will not start the IRQ correctly.

Also override irq_startup()/irq_shutdown() in vmd_init_dev_msi_info(),
so the irq_startup() can invoke the real logic.

Fixes: 54f45a30c0 ("PCI/MSI: Add startup/shutdown for per device domains")

README 

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 reStructuredText 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.
