ALSA: firewire-lib: Add support for AMDTP in-stream and PCM capture
For capturing PCM, this commit adds the functionality to handle in-stream. This is also applied for dual-wire mode. Currently, capturing 32bit samples are supported. When the sequence of in-packet has discontinuity of dbc, in-stream isn't handled and amdtp_streaming_error() returns true.
