now. Activation of the line discipline would deregister the codec device from the platform bus and reregister it again, now as the line discipline provided device. Is this possible with current ASoC framework?
No, not currently. But why would you do that, anyway?
Like I say, I'd suggest always keeping the controls registered and just masking and unmasking from user space - the control indexes get used so removing them will just confuse things.
However, in order for the machine driver to unmask/mask a machine specific control, the codec driver must drop the machine driver a message about the line discipline being activeted/deactivated, right? The only such existing feedback I can see the codec is able to use is via snd_soc_init_card() that calls snd_soc_dai_link.init() in turn. Am I missing something?
