Subject: [PATCH BlueZ 3/5] mesh: Declare internal functions as static
Date:   Tue,  5 Feb 2019 23:38:59 -0800
Message-Id: <20190206073859.29084-1-inga.stotland@intel.com>
Sender: linux-bluetooth-owner@vger.kernel.org
Precedence: bulk

This renames mesh_net_key_refresh_finish() to key_refresh_finish() and
mesh_net_key_phase_two() to key_refresh_phase_wo() and changes the
function declaration to static since they are called only within net.c
