Hi,

This patchset is a fix for a case that AM824 format is used with
non-blocking transmission method in IEC 61883-1/6.

The recent changes for ALSA IEC 61883-1/6 engine brings a bug to miss
received MIDI messages in the case due to wrong data block counter for
calculation of multiplexed MIDI stream index. This bug mainly affects
ALSA oxfw driver.

    tracepoints event for IR context
  ALSA: firewire-lib: fix to process MIDI conformant data channel for
    AM824 format
