Thanks for the cleanup. I tested it on the hardware I have, no problem.
One comment below.

While in general I am in favor of passing error values down the stack,
here I'm not sure. kstrtou8 could return -ERANGE or -EINVAL which makes
no sense as an i2c adapter fault code. According to
Documentation/i2c/fault-codes, -EPROTO or -EIO would be more
appropriate.
