Recent firmware for Fireworks board module have a quirk to start transmission of CIP with non-zero value for its data block counter. In current implementation of ALSA firewire stack, the quirk is handled by 'struct amdtp_stream.ctx_data.tx.first_dbc' with value 0x02. However, the value comes from reverse engineering. It's better to handle this quirk without the explicit value. In a process to parse CIP header, the quirk of data block counter affects decision of sequence index in sequence-multiplexed data channel; i.e. MIDI conformant data channel. In Fireworks, the index is decided by the number of data blocks from top of the same CIP, thus the value of data block counter is useless. This commit adds CIP_UNALIGHED_DBC flag and obsoletes the explicit value for this quirk. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
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.
