commit 1a28dce222a6ece725689ad58c0cf4a1b48894f4 upstream.
Before the video device node is registered, the v4l2_dev.mdev
pointer must be set in order to correctly associate the video
device with the media device. Move the initialization of the
media device up.

commit cf7f34777a5b4100a3a44ff95f3d949c62892bdd upstream.
Prevent NULL (or close to NULL) pointer dereference in various places by
registering the video device only when the V4L2 m2m framework has been set
up.

We never use _ in directory names in the media subsystem, so
rename to test-drivers instead for consistency.
Also update MAINTAINERS with the new path.
