In core function, the instances of fw_device corresponding to firewire device node in system are maintained by IDR. As of kernel v6.0, IDR has been superseded by XArray and deprecated. This commit replaces the usage of IDR with XArray to maintain the device instances. The instance of XArray is allocated statically, and initialized with XA_FLAGS_ALLOC so that the index of allocated entry starts with zero and available as the minor identifier of device node.

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.
