Gary T. Giesen e0fffbce85 config/udev: guard against NULL subsystem in fallback bus id ... config_udev_get_fallback_bus_id() passes the result of udev_device_get_subsystem() straight into strcmp(). That accessor can return NULL when the device has no subsystem, so strcmp(NULL, "pci") dereferences a NULL pointer and the server crashes with a SIGSEGV. The path is reached for any DRM device with no udev ID_PATH property, where config_udev_odev_setup_attribs() falls back to this function. DisplayLink/evdi virtual cards have no ID_PATH; a udev remove of such a card during teardown can present a parent whose subsystem is already gone (reported NULL), and the unchecked strcmp faults. The same NULL-subsystem-into-strcmp class was fixed for the four sibling callers in this file by commit 429ee86a; config_udev_get_fallback_bus_id() was added later (commit 2f53d1cf) without the guard. The preceding parent==NULL case is already guarded here; extend the same defensiveness to the subsystem lookup.
