[PATCH v4 10/21] rockchip/vpu: Fix/re-order probe-error/remove path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jonas Karlman <jonas@xxxxxxxxx>

media_device_cleanup() and v4l2_m2m_unregister_media_controller() were
missing in the probe error path.
While at it, re-order calls in the remove path to unregister/cleanup
things in the reverse order they were initialized/registered.
