4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 30efae3d789cd0714ef795545a46749236e29558 ]
While there are issues related to object lifetime management, unregister the media device first when the driver is being unbound. This is slightly safer.
