--------------------------------

[ Upstream commit 9fa6b4cd ]

hci_le_conn_failed function's documentation says that the caller must
hold hdev->lock. The only callsite that does not hold that lock is
hci_le_conn_failed. The other 3 callsites hold the hdev->lock very
locally. The solution is to hold the lock during the call to
hci_le_conn_failed.
