When introducing CAN-FD support, the .can_fd_mode was not initalized with -1 and due to cm.mask containing the CAN_CTRLMODE_FD bit, it was not ignored when FDMode was not configured but instead disabled. The same thing happened when listen-only mode support was introduced. On chips that do not support these features, this lead to an error: can0: Failed to configure CAN link: Operation not supported Fix it by intializing all the CAN related tristate variables (.can_listen_only, .can_fd_mode and .can_non_iso) to -1.
