David Thompson fddf20b334 gpio: mlxbf3: only get IRQ for device instance 0
[ Upstream commit 10af0273a3 ]

The gpio-mlxbf3 driver interfaces with two GPIO controllers,
device instance 0 and 1. There is a single IRQ resource shared
between the two controllers, and it is found in the ACPI table for
device instance 0.  The driver should not attempt to get an IRQ
resource when probing device instance 1, otherwise the following
error is logged:
  mlxbf3_gpio MLNXBF33:01: error -ENXIO: IRQ index 0 not found

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 reStructuredText 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.
