4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Johan Hedberg <johan.hedberg@xxxxxxxxx> commit 2f99536a5b34d5b0f54723067d68f6cef3f0fdc6 upstream. All LE connections are now triggered through a preceding passive scan and waiting for a connectable advertising report. This means we've got the best possible guarantee that the device is within range and should be able to request the controller to perform continuous scanning. This way we minimize the risk that we miss out on any advertising packets.
