For the other two changes (patches 02 and 03) I'm giving my ack here.
Tested them and after running several playback/capture tasks, looks like the
streaming was ok.

And for the channel swapping issue, I think the thing remains the same.
If I increase the max threshold to something closer to its maximum (0x500)
than, channels swap quite easily. Just:

# aplay -c2 -fdat -I /dev/urandom /dev/zero

But that wouldn't block your two patch Jarkko. I liked this merge.
Code looks cleaner now.
