Subject: [PATCH] crypto: lrw - Check for incorrect cipher name
Git-commit: d38efad2bf1c27fcb375dee9ac8c5c99e02ab38c
Patch-mainline: v4.15-rc1
References: bsc#1051510
If the cipher name does not start with 'ecb(' we should bail out, as done
in the 'create()' function in 'crypto/xts.c'.
Fixes: 700cb3f5fe75 ("crypto: lrw - Convert to skcipher")
