From 5d57e7964c3261827cc718b0e5317ac4950e2f21 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 23 Jan 2015 10:10:38 +0200 Subject: [PATCH] Bluetooth: Check for valid bdaddr in add_remote_oob_data Before doing any other verifications, the add_remote_oob_data function should first check that the given address is valid. This patch adds such a missing check to the beginning of the function.
