The 1394 OHCI driver allocates a DMA coherent buffer for multi-purposes. The buffer is split into three region for specific purposes; i.e. 1/4 for context descriptors of AR request and response as well as 1/2 for self ID handling. This commit uses managed device resource to maintain the lifetime of buffer.

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.
