memory leak due to not kfree(glue).
It is my understanding that since glue is allocated with devm_kzalloc(),
that if the probe function returns and error, glue and everything else
allocated with devm_* will be automatically freed.
If this is not the case, wouldn't devm_kfree() be the appropriate
function instead?

Doesn't match with $subject, I'd put them into a seperate patch.
I disagree. Since these are now automatically freed because of changes
in the probe function, these changes belong in the same patch.
