From a511b35ba4f02cca526c7239723c48445a8b127d Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 11 Dec 2014 21:45:45 +0200 Subject: [PATCH] Bluetooth: Fix incorrect pending cmd removal in pairing_complete() The pairing_complete() function is used as a pending mgmt command cmd_complete callback. The expectation of such functions is that they are not responsible themselves for calling mgmt_pending_remove(). This patch fixes the incorrect mgmt_pending_remove() call in pairing_complete() and adds it to the appropriate changes.
