[PATCH v7 13/27] media: entity: Add only connected pads to the pipeline

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

From: Sakari Ailus <sakari.ailus@linux.intel.com>

A single entity may contain multiple pipelines. Only add pads that were
connected to the pad through which the entity was reached to the pipeline.
