From cdba5281b2496ffbca332e006f258951233bf53d Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Wed, 2 Oct 2013 21:31:52 -0700 Subject: [PATCH] Bluetooth: Restrict SSP setting changes to BR/EDR enabled controllers Only when BR/EDR is supported and enabled, allow changing of the SSP setting. Just checking if the hardware supports SSP is not enough since it might be the case that BR/EDR is disabled. In the case that BR/EDR is disabled, but SSP supported by the controller the not supported error message is now returned.
