Subject[PATCH 4.4 022/241] crypto: gcm - Fix error return code in crypto_gcm_create_common()
Date
From: Wei Yongjun <weiyongjun1@huawei.com>

commit 9b40f79c08e81234d759f188b233980d7e81df6c upstream.

Fix to return error code -EINVAL from the invalid alg ivsize error
handling case instead of 0, as done elsewhere in this function.
