Erk, yeah.  Will fix.

The notify in the name was supposed to cover that (implying that it's
notifying the core rather than actually doing the reset) but it's
obviously not doing the job.  I think wm8400_reset_codec_reg_cache()
should be obvious enough?

Yeah, I considered doing that but decided that it was more trouble than
it was worth - the device has far fewer functions than the WM8350.
