crypto: gcm - fix another complete call in complete fuction
The flow of the complete function (xxx_done) in gcm.c is as follow: void complete(struct crypto_async_request *areq, int err) { struct aead_request *req = areq->data; if (!err) { err = async_next_step(); if (err == -EINPROGRESS || err == -EBUSY) return; } complete_for_next_step(areq, err); } But *areq may be destroyed in async_next_step(), this makes complete_for_next_step() can not work properly. To fix this, one of following methods is used for each complete function. - Add a __complete() for each complete(), which accept struct aead_request *req instead of areq, so avoid using areq after it is destroyed. - Expand complete_for_next_step(). The fixing method is based on the idea of Herbert Xu. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
