    crypto: ghash-clmulni - Fix load failure · 3a020a72
    Wang, Rui Y authored
    ghash_clmulni_intel fails to load on Linux 4.3+ with the following message:
    "modprobe: ERROR: could not insert 'ghash_clmulni_intel': Invalid argument"
    
    After 8996eafd ("crypto: ahash - ensure statesize is non-zero") all ahash
    drivers are required to implement import()/export(), and must have a non-
    zero statesize.
    
    This patch has been tested with the algif_hash interface. The calculated
    digest values, after several rounds of import()s and export()s, match those
    calculated by tcrypt.
