That's absolutely fine - the machine driver is entirely specific to the
hardware it's connecting so things like this are not a problem.  It
already explicitly references the codec and machine drivers anyway.

Yeah, without trusting the application data to leave the bit clear it'd
need some glue in hardware to force the MSB low when not doing control
operations.
