From 75ce208cc44938195f57c55f81c8e4447dd492fb Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 2 Jul 2014 22:42:01 +0300 Subject: [PATCH] Bluetooth: Allow mgmt_device_found events for kernel-side scanning When the kernel is doing LE scanning because of one or more devices added with action 0x00 through the Add Device command we do want to let mgmt_device_found() to proceed with sending an event. This kind of devices are tracked with hdev->pend_le_reports, so check this value before bailing out from the function.
