From 64e7f852c47ce99f6c324c46d6a299a5a7ebead9 Mon Sep 17 00:00:00 2001 From: Ayush Sawal Date: Fri, 4 Oct 2019 10:50:58 -0700 Subject: crypto: af_alg - cast ki_complete ternary op to int when libkcapi test is executed using HW accelerator, cipher operation return -74.Since af_alg_async_cb->ki_complete treat err as unsigned int, libkcapi receive 429467222 even though it expect -ve value. Hence its required to cast resultlen to int so that proper error is returned to libkcapi.
