[ Upstream commit67d33aecd0] Keeping the IRQ chip definition static shares it with multiple instances of the GPIO chip in the system. This is bad and now we get this warning from GPIO library: "detected irqchip that is shared with multiple gpiochips: please fix the driver." Hence, move the IRQ chip definition from being driver static into the struct intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance. This patch is heavily based on the attachment to the bug by Christoph Marz.

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.
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.
