Since the kern_dbpage gets set up in ionic_lif_init() and that function's error path will clean it if needed, the kern_dbpage on teardown should be cleaned in ionic_lif_deinit(), not in ionic_lif_free(). As it is currently we get a double call to iounmap() on kern_dbpage if the PCI ionic fails setting up the lif. One example of this is when firmware isn't responding to AdminQ requests and ionic's first AdminQ call fails to setup the NotifyQ.

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.
