Subject: [PATCH AUTOSEL for 4.14 056/110] crypto: inside-secure - free
 requests even if their handling failed

From: Antoine Ténart <antoine.tenart@...e-electrons.com>

[ Upstream commit 0a02dcca126280595950f3ea809f77c9cb0a235c ]

This patch frees the request private data even if its handling failed,
as it would never be freed otherwise.

Fixes: 1b44c5a60c13 ("crypto: inside-secure - add SafeXcel EIP197 crypto engine driver")
