Where is the above allocated? I don't see it allocated in this driver
AFAICT. If it is not then it does not seem right to free something that
we have not allocated in this driver. I would have assumed it was
allocated by snd_soc_init_platform() in which case it should not be
necessary to free because that function uses devm_kzalloc(). What am I
missing here?

Cheers
Jon
