I believe the problem you are concerned with was fixed by commit
a2187431c395 ("ext4: fix error message when rejecting the default
hash")

And I'm not sure what you meant by your reference to the merge
conflict?  Were you trying to cherry-pick 985b67cd8639 into some other
tree or branch, and that was where you saw the merge conflict?
