Clearly it's not a direct consequence of this commit, that just
introduces a new optional facility which...

...isn't being used by the driver.

Looking at the above it looks like the PCM driver is doing something
very odd - _CONT doesn't make a whole lot of sense on the slave side,
it's related to the clock generation so should have no effect at all on
the slave side.  The driver code looks reasonably sensible though.

What specifically is going wrong here?
