[PATCH 0/3] media: em28xx: fix lifecycle issues

[Hans Verkuil <hverkuil+cisco@kernel.org>]

The first patch switches the em28xx driver to use the v4l2_device
release callback, letting the v4l2 core do all the refcounting
until the last user is gone and it is safe to free all memory.

The second patch drops the 'users' counter and uses the internal
v4l2_fh counter instead. And the last patch switches
video_unregister_device to vb2_video_unregister_device: this
ensures all streaming is stopped when the video device is unregistered.

All this still needs to be tested on real hardware, but that will
have to wait 2-3 weeks.

Regards,

	Hans
