From 7082f6bbec4b39295180730573a7e0152cd8b756 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 1 Aug 2023 21:50:26 +0300 Subject: pipeline: raspberrypi: vc4: Unconditionally create embedded data stream The mainline Unicam driver unconditionally creates the embedded data video device. Create the corresponding stream unconditionally. Drop the warning in case of mismatch between Unicam and the CamHelper, as this becomes a normal situation when the sensor doesn't support emebedded data.
