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
