Bluetooth: hci_core: Fix unbalanced unlock in set_device_flags()
There is only one "goto done;" in set_device_flags() and this happens *before* hci_dev_lock() is called, move the done label to after the hci_dev_unlock() to fix the following unlock balance: [ 31.493567] ===================================== [ 31.493571] WARNING: bad unlock balance detected! [ 31.493576] 5.17.0-rc2+ #13 Tainted: G C E [ 31.493581] ------------------------------------- [ 31.493584] bluetoothd/685 is trying to release lock (&hdev->lock) at: [ 31.493594] [<ffffffffc07603f5>] set_device_flags+0x65/0x1f0 [bluetooth] [ 31.493684] but there are no more locks to release! Note this bug has been around for a couple of years, but before commit fe92ee6425a2 ("Bluetooth: hci_core: Rework hci_conn_params flags") supported_flags was hardcoded to "((1U << HCI_CONN_FLAG_MAX) - 1)" so the check for unsupported flags which does the "goto done;" never triggered.
