The PCM interface in SST driver is cmds only, this patch changes the interface to open, close and cmd interface.
This allows SST driver to keep easy track of handles open

This should be >= instead of > or we go passed the end of the array.
Also the arrays are declared with size MAX_NUM_STREAMS. This is the
only place that uses MAX_NUM_STREAMS_MFLD. It seems like asking for
trouble to use two variables for the same information. I've changed
everything to use MAX_NUM_STREAMS.
This bug isn't really harmful. In the worst case, if you enabled
debugging then you would see a message.

str_id was unsigned, so check for (str_id <= 0) made no sense.
Made it signed.

This is the Intel SST audio driver.
As compared to the previous versions it has all the printks and other stuff
noted cleaned up and more hardware support. The Aava support is disabled in
this patch (is_aava resolves to 0) because the Aava board detection logic
is not yet upstream.
The driver itself is a combination of a traditional ALSA driver and a
hardware assisted offload driver which can play audio while the processor
is asleep but which can't do all the more interactive stuff.
In the general case most software would use the ALSA interface, but the
other interface is needed for certain classes of use such as music playback
on highly power consumption sensitive devices.
This is going to staging primarily because it depends upon the staging memrar
driver.
