The device is actually released only after the refcnt of the hpriv structure is 0, which means all its contexts were closed. If we reset the device while a context is still open, there are possibilities for unexpected behavior and crashes. For example, if the process has a mapping of a register block that is now currently being reset, and the process writes/reads to that block during the reset, the device can get stuck.

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.
