From 6eb5fcc416f127f220b9177a5c9ae751cac1cda8 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Tue, 16 Apr 2024 15:34:45 -0400 Subject: Bluetooth: MGMT: Fix failing to MGMT_OP_ADD_UUID/MGMT_OP_REMOVE_UUID These commands don't require the adapter to be up and running so don't use hci_cmd_sync_queue which would check that flag, instead use hci_cmd_sync_submit which would ensure mgmt_class_complete is set properly regardless if any command was actually run or not.
