[PATCH v9 10/13] media: cadence: csi2rx: Populate subdev devnode

From: Jai Luthra
Date: Fri Aug 11 2023 - 06:48:24 EST


From: Pratyush Yadav <p.yadav@xxxxxx>

The devnode can be used by media-ctl and other userspace tools to
perform configurations on the subdev. Without it, media-ctl returns
ENOENT when setting format on the sensor subdev.
