It does not - all CRYPTO related code is limited into the lrng_drbg.c, 
lrng_kcapi.c and lrng_jent.c which are all guarded by a Kconfig option.

Right - this should now be fixed with a depends on CRYPTO for the 
aforementioned 3 C files which have an equal entry in Kconfig.

With the changes to the Kconfig file as explained in the other emails, I can 
successfully compile the LRNG without the crypto API being enabled.

Thank you for pointing that one out.
