+Subject: [PATCH 011/116] crypto: starfive - Pad adata with zeroes
+
+Aad requires padding with zeroes up to 15 bytes in some cases. This
+patch increases the allocated buffer size for aad and prevents the
+driver accessing uninitialized memory region.
+
+v1->v2: Specify reason for alloc size change in descriptions.
