From: Bard Liao yung-chuan.liao@linux.intel.com

MOD_INIT_INSTANCE IPC for a copier only contains the sink format for output pin 0. Any additional output pins that are used need to have their sink format set using the LARGE_CONFIG_SET IPC message. Otherwise, firmware will report error or crash due to NULL format is used.
