[PATCH v4 06/11] media: cadence: csi2rx: Populate subdev devnode

From: Pratyush Yadav
Date: Wed Sep 15 2021 - 08:03:21 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.
