At the moment, the dpio-driver allocates an MC portal at probe time and frees it right after usage. The same thing happens on the remove path. This behavior could lead to scenarios where an MC portal is available for use at probing but not longer free on the remove path which could lead to unproper unbind of resources. Change the driver's behavior in such a way that an MC portal is allocated at probe and kept until the DPIO device is removed. This will ensure that at any time after a DPIO device was successfully probed, all its dependencies will be met.

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.
