Subject: media: ivsc: csi: Don't parse remote endpoints
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Mon Oct 16 10:18:29 2023 +0300
The driver parsed, besides its own endpoint on the sink, the remote
upstream endpoint that most likely is a sensor, and took the number of
lanes from that. Instead obtain the number of lanes from the local
endpoint.
