From a2cb01de1cb1db05b946e0132aeecbb514c57024 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 19 Feb 2015 17:38:07 +0200 Subject: [PATCH] Bluetooth: Fix checking for pending Set SSP in Set HS handler Changing the HS setting requires that SSP is enabled, however so far the code only checked for the SSP flag but not a potentially ongoing Set SSP operation. This patch adds a check for a pending Set SSP command in the Set HS handler, and returns a 'busy' error if one is found.
