From 52c2575db8faa1d93227a92a32deb2cd66b96614 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Fri, 13 Oct 2023 09:15:48 +0200 Subject: media: v4l: subdev: Store the sub-device in the sub-device state 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.
