From f8523598ee608a8c4d1f3bbd3639785be3321111 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Fri, 9 Sep 2011 18:56:26 -0300 Subject: [PATCH] Bluetooth: Check 'dev_class' in mgmt_device_found() The mgmt_device_found event will be used to report LE devices found during discovery procedure. Since LE advertising reports events doesn't have class of device information, we need to check if 'dev_class' is not NULL before copying it. Signed-off-by: Andre Guedes Signed-off-by: Gustavo F.
