The function should be exactly the same, dependencies on needed modules are set.

In cryptsetup we always report dm target + kernel version,
so we know that since version 5.4 it uses crypto API for ESSIV.
I think version bump here is really not so important.

Just my two cents :)

Anyway, thanks everyone.
