From f4869e2adb7ab9d09a9335b4e26a63ec413f2c6f Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 2 Jul 2014 17:37:32 +0300 Subject: [PATCH] Bluetooth: Pass store hint to mgmt_new_conn_param The calling functions of mgmt_new_conn_param have more information about the parameters, such as whether the kernel is tracking them or not. It makes therefore sense to have them pass an initial store_hint value to the mgmt_new_conn_param function.
