ALSA: firewire-lib: Add 'direction' member to 'amdtp_stream' structure
This patch adds 'direction' member to amdtp_stream structure to indicate its direction. This patch also adds 'direction' argument to amdtp_stream_init() function to determine its direction. The amdtp_stream_init() function is exported and used by firewire-speakers and dice so this patch also affects them. This patch just add them. Actual implementation will be done by followed patches.
