Unnecessary double space


I did notice this just after I sent the patch!
enum stream_state {
Q6ASM_STREAM_IDLE = 0,
Q6ASM_STREAM_STOPPED,

why would we need a lock for compress case?
bytes_received counter is updated as part of Ack and referenced in the irq context in the event_handler callback from dsp, this lock is to protect it !
