[ Upstream commit 41efa431244f6498833ff8ee8dde28c4924c5479 ] The IMS related functions (pci_create_ims_domain(), pci_ims_alloc_irq(), and pci_ims_free_irq()) are not declared when CONFIG_PCI_MSI is disabled. Provide definitions of these functions for use when callers are compiled with CONFIG_PCI_MSI disabled.

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.
