You may wish to double read the message above, as it's quite confusing =)
Yes it is ;) I have left one spinlock around the dma_op_mode, when it also protects the mcbsp->active, so that is why that last sentence.
I have to confess that I'm still not entirely clear what the lock is supposed to be doing or why it's OK to drop it. I gather that it's just that dmap_on_mode() doesn't need a lock at all?
