From ca5c4be716c50a245157d67b6e1dc97b2d89cdd4 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 25 Mar 2014 10:30:46 +0200 Subject: [PATCH] Bluetooth: Don't send device found events during passive scanning Passive LE scanning is only used by the kernel-internal connection establishment procedure. It makes therefore little sense to send device found events to user space.
