Well, the only one I found that does this is the flash-led-class :-)

By default, serialise open and release internal ops using a mutex.
The underlying problem is that a large proportion of the drivers do use
v4l2_fh_is_singular() in their open() handlers (struct
v4l2_subdev_internal_ops). v4l2_subdev_open(), .open file operation handler
of the V4L2 sub-device frame
