Title
s390/crypto: Fix handling of EBUSY in PHMAC when req is pushed to crypto engine
Summary
In the Linux kernel, the following vulnerability has been resolved: s390/crypto: Fix handling of EBUSY in PHMAC when req is pushed to crypto engine When a request is transferred to the engine via crypto_transfer_hash_request_to_engine() there are two return codes signaling a successful transfer: EINPROGRESS and EBUSY. However the correct handling of EBUSY was missing and has been added as a return code indicating a successful transfer to the crypto engine.
