Marc Zyngier 443ed62ef8 PCI: dwc: Fix inner MSI IRQ domain registration
[ Upstream commit 0414b93e78d87ecc24ae1a7e61fe97deb29fa2f4 ]

On a system that uses the internal DWC MSI widget, I get this
warning from debugfs when CONFIG_GENERIC_IRQ_DEBUGFS is selected:

  debugfs: File ':soc:pcie@fc000000' in directory 'domains' already present!

This is due to the fact that the DWC MSI code tries to register two
IRQ domains for the same firmware node, without telling the low
level code how to distinguish them (by setting a bus token). This
further confuses debugfs which tries to create corresponding
files for each domain.

Fix it by tagging the inner domain as DOMAIN_BUS_NEXUS, which is
the closest thing we have as to "generic MSI".

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.
