If we remove a GPIO chip that is also an interrupt controller with users not having freed some interrupts, we'll end up leaking resources as indicated by the following warning: remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'gpio' As there's no way of notifying interrupt users about the irqchip going away and the interrupt subsystem is not plugged into the driver model and so not all cases can be handled by devlinks, we need to make sure to free all interrupts before the complete the removal of the provider.

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.
