Thanks!

Sorry for not doing this before submitting. Will send the followup soon.

I have put the line discipline code into the machine driver for two reasons: 1. For me, the actual code is much more machine than codec specific. 2. It was much easier to update the codec structure instance with machine's provided hw_write() rather than fiddle with adding a new member to the structure definition for passing a machine callback to the line discipline functions.
If you think we can find any use cases for drivers supporting codec/modem combination other than CX20442 on Amstrad Delta, I can agree with you on moving the line discipline code out of the machine driver, but instead of pushing it down to the codec I would rather se it as a separate module. Anyway, I think that some kind of support on the ASoC top level for this case could be helpfull.

I'll add a few words to the followup.
Thanks, Janusz
