As we now have deferred probing, we can use a custom mechanism and finally get rid of this legacy interface from the i2c core.

Changes since last time: Added two test tags from the Debian PPC list.
I'd love to have that in 4.2, so I can get rid of that legacy interface. I can take it via I2C but ALSA looks like the proper path to me.
I applied the patch now. Sorry for the late response, as I've been on vacation for last two weeks.
thanks,
Takashi
