[PATCH AUTOSEL 4.14 01/35] media: omap3isp: Unregister media device as first

From: Sasha Levin

[ 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.
