[PATCH 01/17] alsa: Add a ports array to pa_alsa_path

[tanu.kaskinen@xxxxxxxxxxxxxxx (Tanu Kaskinen)]

One path can be the basis for multiple ports. Having just a single
port pointer in pa_alsa_path doesn't make sense, and I'll remove that
pointer once I have converted the users of that pointer to use this
new ports array.
