Huacai Chen b56dee6c9b irqchip/loongarch-cpu: Fix return value of lpic_gsi_to_irq()
commit 81a91abab1 upstream.

lpic_gsi_to_irq() should return a valid Linux interrupt number if
acpi_register_gsi() succeeds, and return 0 otherwise. But lpic_gsi_to_irq()
converts a negative return value of acpi_register_gsi() to a positive value
silently.

Convert the return value explicitly.

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 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.
