From 16324fc8def1c08a92261089aaf503aca3381aa6 Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Fri, 12 Mar 2021 09:24:37 -0700 Subject: [PATCH] remoteproc: Remove useless check in rproc_del() Whether started at probe() time or thereafter from the command line, a remote processor needs to be shut down before the final cleanup phases can happen. Otherwise the system may be left in an unpredictable state where the remote processor is expecting the remoteproc core to be providing services when in fact it no longer exist. Invariably calling rproc_shutdown() is fine since it will return immediately if the remote processor has already been switched off.
