2019-01-21media: imx: queue subdev events to reachable video devicesSteve Longerbeam
In order to receive events generated by subdevices on the video capture nodes, those events need to be forwarded to the subdevice's list of reachable video capture devices. Note this will queue the event to a video device even if there is no actual _enabled_ media path from the sub-device to the video device. So a future improvement is to skip the video device if there is no enabled path to it from the sub-device. The entity->pipe pointer can't be used for this check because in imx-media a sub-device can be a member to more than one streaming pipeline at a time.
