Ah. It's that that third one that really introduced the dependency so possibly
only that one should be listed with a fixes tag.  However the right fix
at that point was to select CRYPTO_DES which then changed to CRYPTO_LIB_DES
only after the second patch.

It's not a fix for the first patch so that should probably not be there.

Otherwise, looks correct to me.
