When working with a bus device, many operations are only possible while the device is still bound. The &Device<Bound> type represents a proof in the type system that you are in a scope where the device is guaranteed to still be bound. Since we deregister irq callbacks when unbinding a device, if an irq callback is running, that implies that the device has not yet been unbound. To allow drivers to take advantage of that, add an additional argument to irq callbacks.

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.
