[0/3] ALSA: firewire-lib: fixes for processing packets without CIP header

Message

Hi,

In kernel v4.12, a series of patch was applied to IEC 61883-1/6 packet
streaming engine in ALSA firewire stack to process isochronous packet
without CIP header. But this included some bugs. Especially, for capture
PCM substream, the engine handles PCM frames for applications as four
times against real time.

This patchset fixes the bugs.

Takashi Sakamoto (3):
  ALSA: firewire-lib: fix wrong handling payload_length as
    payload_quadlet
  ALSA: firewire-lib: fix wrong assignment for
    'out_packet_without_header' tracepoint
  ALSA: firewire-lib: use the same print format for 'without_header'
    tracepoints
