[ Upstream commit 2a2b09c867fdac63f430a45051e7bd0c46edc381 ]
In lk 5.11.0-rc2 connecting a USB based Silicon Labs HID to I2C
bridge evaluation board (CP2112EK) causes this warning:
gpio gpiochip0: (cp2112_gpio): detected irqchip that is shared
with multiple gpiochips: please fix the driver
Simply copy what other gpio related drivers do to fix this
particular warning: replicate the struct irq_chip object in each
device instance rather than have a static object which makes that
object (incorrectly) shared by each device.

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.
