Subject: [PATCH v4 13/31] media: entity: Add only connected pads to the pipeline
Date: Thu, 28 Mar 2019 21:05:50 +0100	[thread overview]
Message-ID: <20190328200608.9463-14-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20190328200608.9463-1-jacopo+renesas@jmondi.org>

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.
