> which was merged through the crypto tree for v5.3, changed ppp_mppe.c to
> use the new arc4_crypt() library function rather than access RC4 through
> the dynamic crypto_skcipher API.
> Meanwhile commit aad1dcc4f011 ("ppp: mppe: Add softdep to arc4") was
> merged through the net tree and added a module soft-dependency on "arc4".
> The latter commit no longer makes sense because the code now uses the
> "libarc4" module rather than "arc4", and also due to the direct use of
> arc4_crypt(), no module soft-dependency is required.
> So revert the latter commit.
