Subject: media: v4l: subdev: Store the sub-device in the sub-device state
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Fri Oct 13 09:15:48 2023 +0200
Store the sub-device in the sub-device state. This will be needed in e.g.
validating pad number when retrieving information for non-stream-aware
users. There are expected to be more needs for this in the future.
