ALSA: firewire-lib: pass data block counter to data block processing layer
This is a preparation for future commit that 'struct amdtp_stream.data_block_count' does not represent the value of data block count for current data block. However, data block count is required for calculation of sequence index in sequence-multiplied data channel. Some of data block processing layer require it; e.g. for AM824 data block. This commit passes data block count to the processing layer. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
