From 55af49a8fe85278ea244e72d2d264cf5e0941c61 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 2 Jul 2014 17:37:26 +0300 Subject: [PATCH] Bluetooth: Add specific connection parameter clear functions In some circumstances we'll need to either clear only the enabled parameters or only the disabled ones. This patch adds convenience functions for this purpose.
