[PATCH v6 08/14] media: cadence: csi2rx: Populate subdev devnode

From: Pratyush Yadav
Date: Fri Jan 21 2022 - 09:30:03 EST


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.
