Subject: [PATCH] crypto: atmel-aes - fix the keys zeroing on errors
Git-commit: 5d804a5157dbaa64872a675923ae87161165c66b
Patch-mainline: v4.17-rc1
References: bsc#1051510
The Atmel AES driver uses memzero_explicit on the keys on error, but the
variable zeroed isn't the right one because of a typo. Fix this by using
the right variable.
Fixes: 89a82ef87e01 ("crypto: atmel-authenc - add support to authenc(hmac(shaX), Y(aes)) modes")
