While the lookup/initialization code already supports multiple memory regions per device, the release code will only ever release the first matching memory region. Enhance the code to release all matching regions. Each attachment of a region to a device is uniquely identifiable using a struct device pointer and a pointer to the memory region's struct reserved_mem.

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.
