From f640ee98bbeaa169684a571e0b96bea563bb6015 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 8 Oct 2015 12:35:42 +0200 Subject: [PATCH] Bluetooth: Fix basic debugfs entries for unconfigured controllers When the controller is unconfigured (for example it does not have a valid Bluetooth address), then the basic debugfs entries for dut_mode and vendor_diag are not creates. Ensure they are created in __hci_init and also __hci_unconf_init functions. One of them is called during setup stage of a new controller.
