Subject: media: rcar-vin: Disallow unbinding and binding of individual VINs Author: Niklas Söderlund <[email protected]> Date: Sun Nov 28 14:24:47 2021 +0100 The VIN driver have an internal concept of capture groups that covers multiple instances of the driver. This is handled using the shared media graph and a single notifier shared between all VIN instances. This design do not work well if an individual VIN where to be unbound on its own. The design could be improved up on to allow for this but would require large changes in the v4l2-async framework. To avoid the situation suppress the bind and unbind nodes in sysfs.
