Subject: [PATCH v1 2/3] staging: media: ipu3: Return buffers outside of needless locking
Date: Thu, 20 Jun 2024 23:45:42 +0900 [thread overview]
Message-ID: <20240620145820.3910239-3-mstaudt@chromium.org> (raw)
In-Reply-To: <20240620145820.3910239-1-mstaudt@chromium.org>
In imgu_vb2_start_streaming()'s error path, imgu_return_all_buffers()
is outside the streaming_lock and after the call to
video_device_pipeline_stop().
Let's apply the same order in imgu_vb2_stop_streaming() as well.
