I recommend to build the Socket-CAN kernel modules out-of-tree as
described in the README mentioned in my previous mail, at least for
getting started (less error prune).

As written in my previous mail, you need to use the old SysFS interface
enabling CONFIG_CAN_DEV_SYSFS:
config CAN_DEV_SYSFS
bool "Support for sysfs interface (deprecated)"
