From 118da70b760f04bb2b8130ced97a9f9cc173440a Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 20 Jan 2013 14:27:20 +0200 Subject: [PATCH] Bluetooth: Fix checking for valid disconnect parameters in unpair_device The valid values for the Disconnect parameter in the Unpair Device command are 0x00 and 0x01. If any other value is encountered the command should fail with the appropriate invalid params response.
