Giovanni Cabiddu c971e6a1c8 crypto: qat - disable registration of algorithms ... commit 8893d27ffc upstream. The implementations of aead and skcipher in the QAT driver do not support properly requests with the CRYPTO_TFM_REQ_MAY_BACKLOG flag set. If the HW queue is full, the driver returns -EBUSY but does not enqueue the request. This can result in applications like dm-crypt waiting indefinitely for a completion of a request that was never submitted to the hardware. To avoid this problem, disable the registration of all crypto algorithms in the QAT driver by setting the number of crypto instances to 0 at configuration time.
