The function acpi_gsi_to_irq() must return 0 on success as the caller
ghes_probe expects an 0 for success. This change also matches x86
implementation.
This patch was submitted around 4.5 timeframe but wasn't pushed because
it didn't fix a real problem. Now that RAS/GHES patches are in kernel,
this fixes an error seen on a Mustang (arm64) platform:
GHES: Failed to map GSI to IRQ for generic hardware error source: 2
GHES: probe of GHES.2 failed with error 81

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.
