In kernel API of Linux FireWire subsystem, handlers of isochronous receive (IR) context can get context headers as an argument of callback. When 4 byte header is used, the context header includes isochronous packet header for each packet. When 8 byte header is used, it includes isochronous cycle as well. ALSA IEC 61883-1/6 engine uses 4 byte header, and computes isochronous cycle from the cycle of interrupt. The usage of 8 byte header can obsolete the computation. Furthermore, this change works well for a case that a series of packet in one interrupt includes skipped isochronous cycle, This commit uses 8 byte header to handle isochronous cycle.

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.
