The WARN below triggers during the removal of an MST port. The problem is that the parent device's (the connector's kdev) sysfs directory is removed recursively when the connector is unregistered (even though the I2C device holds a reference on the parent device). To fix this set first the Peer Device Type to none which will remove the I2C device. Note that atm, inconsistently, the parent of the I2C device is initially set to the DRM kdev and after a Connection Status Notification the parent may be reset to be the connector's kdev. This problem is addressed by the next patch.
