[alsa-devel] [PATCH 0/3 v3] firewire-lib: support tracepoints to dump a part of packet data

Hi,

This patchset updates my RFCv2, and go for merging.

[alsa-devel] [RFC][PATCH 0/3 v2] firewire-lib: support Linux tracing framework
to dump a part of packet data
http://mailman.alsa-project.org/pipermail/alsa-devel/2016-April/106950.html

The motivation of this patchset is to check the sequence of packet from/to
audio and music units on IEEE 1394 bus. When the units have some quirks or
ALSA firewire stack includes some bugs, we can work to seek them with Linux
tracing framework.

Changes:
 - Improve commit comments.
 - Improve Python3 script in commit comment for NODATA/NOINFO packets.
 - Move the position of trace_out_acket() so that the index of packet starts 0.
