Hi,

The following series will enable multi-stream support for playback and capture
streams.
Currently only a single PCM can be connected to a DAI, with the multi-stream
support it is possible to connect multiple PCMs to a single DAI.

To achieve this we need to make sure that DAIs/AIF are only set up once since
other stream could be connected to it later.

We also need to introduce reference or use counting for widgets to make sure
that they are not going to be destroyed while other streams are still using
them.

With the multi-stream support we also need to extend our current locking scheme
which worked well for simple paths.

The first patch was sent to the mailing list, but it is not yet applied and I
have included in this series as it is a direct dependency:

Regards,
Peter
