This appears to be the lock for the USB interface\ndevice. The Mediatek btusb code gets called via this path:\n\n Workqueue: hci0 hci_power_on [bluetooth]\n Call trace:\n usb_driver_claim_interface\n btusb_mtk_claim_iso_intf\n btusb_mtk_setup\n hci_dev_open_sync\n hci_power_on\n process_scheduled_works\n worker_thread\n kthread\n\nWith the above call trace the device lock hasn't been claimed. Claim\nit.\n\nWithout this fix, we'd sometimes see the error \"Failed to claim iso\ninterface\". Sometimes we'd even see worse errors, like a NULL pointer\ndereference (where `intf->dev.driver` was NULL) with a trace like:\n\n Call trace:\n usb_suspend_both\n usb_runtime_suspend\n __rpm_callback\n rpm_suspend\n pm_runtime_work\n process_scheduled_works\n\nBoth errors appear to be fixed with the proper locking."
