Next time you may use --subject-prefix to specify the version of the
patch. This one in particular is "PATCH v2".
I'm pretty sure Greg or any maintainer will ask you to split your
patch to two: one per driver.

I think in the subject line is better to write something like
"at24: convert to use devm_kzalloc".
For at25 accordingly.

It's good to keep the style here untouched, because it follows CodingStyle.
thus

return ...

No need to remove this empty line.
