  dev_err_probe() already display the error code. There is no need to
duplicate it explicitly in the error message.

i2c_transfer returns the number of transmitted messages. So I think the 
values 0 <= ret < 2 also need to be handled.

Ok, agreed.

If ok for you, I'll send a follow-up patch when/if this one is applied,
because what you spotted is unrelated to the dev_err_probe() behavior.
