This stuff probably shouldn't be in the machine driver since pretty much
all machine drivers are going to want exactly the same code - it should
be in the library code.  Probably best to have them take hw_params
rather than require the machine driver to decode the format, rate and
channel since that'll save a bit of per driver boiler plate if they
don't otherwise need that information.

As I said last time ideally machine drivers shouldn't have to see this
at all, of course.

Otherwise this series all looks basically OK.  Liam is travelling at the
minute so it'll probably be the weekend at the earliest (more likely
early next week) before he has a chance to look at it.
