When CONFIG_DEV_COREDUMP is not defined, there is this error drivers/bluetooth/btmtk.c: In function ‘btmtk_process_coredump’: drivers/bluetooth/btmtk.c:386:44: error: ‘struct hci_dev’ has no member named ‘dump’ 386 | schedule_delayed_work(&hdev->dump.dump_timeout, | ^~ The runtime IS_ENABLED(CONFIG_DEV_COREDUMP) is not enough to prevent the compiletime error of accessing the dump element of hci_dev. So switch to #ifdef.
