From 57d8154f15e89f53dfb412f4ed32ebe3c3d755a0 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Fri, 15 Nov 2019 13:49:09 +0000 Subject: [PATCH] crypto: atmel-aes - Change data type for "lastc" buffer In case of in-place decryption, the "lastc" buffer is used to copy the last ciphertext block before the decryption of the message. It is later used to update the req->iv of the skcipher_request. "lastc" variable is not used to interact with the hardware, there is no restriction to be of type "u32". Change the type of "lastc" to "u8".
