Now that we were able to catch you, I will use the opportunity to
clarify the doubts I had.

- struct mutex lock in struct virtio_i2c, I don't think this is
required since the core takes care of locking in absence of this.
This is likely correct.
OK. Then I will remove the lock.
Let me have a look first, please.


Sure. Thank you.


- Use of I2C_CLASS_DEPRECATED flag, I don't think it is required for
new drivers.
This is definately correct :)
Do you mean a new driver doesn't need to set the following ?

vi->adap.class = I2C_CLASS_DEPRECATED;

Just leave the class to be 0 ?
Yes. DEPRECATED is only for drivers which used to have a class and then
chose to remove it.


Got it. Thanks for your clarification.
