Takashi Sakamoto 8820a4cf0c ALSA: firewire-digi00x: handle all MIDI messages on streaming packets 
At a commit 9dc5d31cdc ("ALSA: firewire-digi00x: handle MIDI messages in
isochronous packets"), a functionality to handle MIDI messages on
isochronous packet was supported. But this includes some of my
misunderstanding. This commit is to fix them.

For digi00x series, first data channel of data blocks in rx/tx packet
includes MIDI messages. The data channel has 0x80 in 8 bit of its MSB,
however it's against IEC 61883-6. Unique data format is applied:
 - Upper 4 bits of LSB represent port number.
  - 0x0: port 1.
  - 0x2: port 2.
  - 0xe: console port.
 - Lower 4 bits of LSB represent the number of included MIDI message bytes;
   0x0/0x1/0x2.
 - Two bytes of middle of this data channel have MIDI bytes.

Especially, MIDI messages from/to console surface are also transferred by
isochronous packets, as well as physical MIDI ports.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
