commite4313be159upstream. MSI domain callback .alloc() (implemented by advk_msi_irq_domain_alloc() function) should return zero on success, since non-zero value indicates failure. When the driver was converted to generic MSI API in commitf21a8b1b68("PCI: aardvark: Move to MSI handling using generic MSI support"), it was converted so that it returns hwirq number. Fix this.

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.
