Subject: [PATCH] crypto: tcrypt - fix buffer lengths in test_aead_speed()
Git-commit: 7aacbfcb331ceff3ac43096d563a1f93ed46e35e
Patch-mainline: v4.15-rc1
References: bsc#1051510
Fix the way the length of the buffers used for
encryption / decryption are computed.
For e.g. in case of encryption, input buffer does not contain
an authentication tag.
