commit 9a5875f14b0e3a13ae314883f1bb72b7f31fac07 upstream. When replugging the device the following message shows up: gpio gpiochip2: (dln2): detected irqchip that is shared with multiple gpiochips: please fix the driver. This also has the effect that interrupts won't work. The same problem would also show up if multiple devices where plugged in. Fix this by allocating the irq_chip data structure per instance like other drivers do. I don't know when this problem appeared, but it is present in 5.10.

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.
