If adding support incrementally works for such an interface, this makes

So, where are we? As I understand, this v10 does not support I2C
transactions (or I2C_RDWR as you said). But you want to support all
clients. So, this doesn't match, or?

I hope we can have a minimum working driver get merged first so that we can have a base.

The v10 has three remaining problems:

    1. To remove vi->adap.class = I2C_CLASS_DEPRECATED; (already confirmed by Wolfram)

    2. Use #ifdef CONFIG_PM_SLEEP to replace the "__maybe_unused" (already confirmed by Arnd)

    3. It seems the I2C core takes care of locking already, so is it safy to remove "struct mutex lock in struct virtio_i2c"?

        (Raised by Viresh, still need Wolfram's confirmation)
