From: Gustavo Padovan <gustavo.padovan@collabora.com>

Drivers that use videobuf2 are capable of using fences and
should report that to userspace.

The coding style is following what each drivers was already
doing.

I think this can be simplified for most drivers: you can set this
flag in the v4l_querycap function if vdev->queue is not NULL or if
m2m_ctx is set in struct v4l2_fh.

I believe all non-m2m drivers that use vb2 set vdev->queue. But not
all m2m drivers will set m2m_ctx, so that will need to be checked.

In other words, this way you only need to modify m2m drivers that
do not set m2m_ctx.

Regards,

	Hans
