Takashi Iwai e9e02819a9 ALSA: seq: Automatic conversion of UMP events
This patch enables the automatic conversion of UMP events from/to the
legacy ALSA sequencer MIDI events.  Also, as UMP itself has two
different modes (MIDI 1.0 and MIDI 2.0), yet another converters
between them are needed, too.  Namely, we have conversions between the
legacy and UMP like:
  - seq legacy event -> seq UMP MIDI 1.0 event
  - seq legacy event -> seq UMP MIDI 2.0 event
  - seq UMP MIDI 1.0 event -> seq legacy event
  - seq UMP MIDI 2.0 event -> seq legacy event

and the conversions between UMP MIDI 1.0 and 2.0 clients like:
  - seq UMP MIDI 1.0 event -> seq UMP MIDI 2.0 event
  - seq UMP MIDI 2.0 event -> seq UMP MIDI 1.0 event

The translation is per best-effort; some MIDI 2.0 specific events are
ignored when translated to MIDI 1.0.

README

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.
