dm crypt: Initialize crypto wait structures
Use the DECLARE_CRYPTO_WAIT() macro to properly initialize the crypto wait structures declared on stack before their use with crypto_wait_req(). Fixes: 39d13a1ac41d ("dm crypt: reuse eboiv skcipher for IV generation") Fixes: bbb1658461ac ("dm crypt: Implement Elephant diffuser for Bitlocker compatibility") Cc: stable@vger.kernel.org Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
