I did it, here is the result:

    random: fix crng_ready() test
    
    commit 43838a23a05fbd13e47d750d3dfd77001536dd33 upstream.
    
    The crng_init variable has three states:
    
    0: The CRNG is not initialized at all
    1: The CRNG has a small amount of entropy, hopefully good enough for
       early-boot, non-cryptographical use cases
    2: The CRNG is fully initialized and we are sure it is safe for
       cryptographic use cases.
    
    The crng_ready() function should only return true once we are in the
    last state.  This addresses CVE-2018-1108.
