Subject: [PATCH 0/2] media: mc: Simplify media pipeline start/stop
Date: Thu, 13 Jan 2022 17:00:40 +0200 [thread overview]
Message-ID: <20220113150042.15630-1-laurent.pinchart+renesas@ideasonboard.com> (raw)
Hello,
This small series simplifies the implementation of the
media_pipeline_start() function (and to a lesser extend, the
media_pipeline_stop() function as well) by avoiding unnecessary graph
walks.
Patch 1/2 adds a small inline helper function to avoid direct access to
the media_entity.stream_count field in drivers, making it easier in
patch 2/2 to rework the implementation (dropping the stream_count field)
without disturbing drivers. Please see patch 2/2 for a detailed
explanation of the simplification.
