We found out that tpa6130a2 device is being initialized before i2c_2 bus is initialized. So that is reason why tpa6130a2 fails... Any idea why kernel first try to initialize one i2c device even before bus itself is initialized?

And this problem is there for a long time... -- Pali Rohár pali.rohar@gmail.com
