Subject: [PATCH 10/11] media: exynos4-is: Prevent duplicate call to media_pipeline_stop
Date: Sat, 25 Apr 2020 19:26:49 -0700	[thread overview]
Message-ID: <BN6PR04MB0660DB1C884EE9F9C7D94857A3AE0@BN6PR04MB0660.namprd04.prod.outlook.com> (raw)
In-Reply-To: <20200426022650.10355-1-xc-racer2@live.ca>

media_pipeline_stop can be called from both release and streamoff,
so make sure they're both protected under the streaming flag and
not just one of them.

This probably became noticeable after commit 2a2599c66368 ("[media] media:
entity: Catch unbalanced media_pipeline_stop calls") was merged as it
added a WARN.
