    Subject[PATCH 3.16 250/370] crypto: api - Clear CRYPTO_ALG_DEAD bit before registering an alg
    3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Salvatore Benedetto <salvatore.benedetto@intel.com>

    commit d6040764adcb5cb6de1489422411d701c158bb69 upstream.

    Make sure CRYPTO_ALG_DEAD bit is cleared before proceeding with
    the algorithm registration. This fixes qat-dh registration when
    driver is restarted
