4.19-stable review patch. If anyone has any objections, please let me know. ------------------ [ Upstream commit 32388d6ef7cffc7d8291b67f8dfa26acd45217fd ] While there are issues related to object lifetime management, unregister the media device first, followed immediately by other device nodes when the driver is being unbound. Only then the resources needed by the driver may be released. This is slightly safer.
