VIDIOC_SUBSCRIBE_EVENT for V4L2_EVENT_CTRL regression?

Hi All I'm testing with 4.19 and finding that testEvents in v4l2-compliance is failing with ""failed to find event for control '%s' type %u", ie it hasn't got the event for the inital values. This is with the various BCM2835 drivers that I'm involved with. Having looked at the v4l2-core history
