From 5ec12f1c7bac891c3268dd6e441a3755ca2b46e0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Sat, 23 Sep 2023 12:08:06 +0200 Subject: [PATCH] crypto: engine - Make crypto_engine_exit() return void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All callers ignore the return value, so simplify by not providing one. Note that crypto_engine_exit() is typically called in a device driver's remove path (or the error path in probe), where errors cannot be handled anyhow.
