From c29d2444170a4e0709331e357a2738a02666a633 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 16 Jun 2014 19:25:14 +0300 Subject: [PATCH] Bluetooth: Fix missing NULL check for smp_chan_create() return value The smp_chan_create function may return NULL, e.g. in the case of memory allocation failure, so we always need to check for this.
