With upstream commit bb208f14 (can: fix handling of unmodifiable configuration options) a new can_validate() function was introduced. When invoking 'ip link set can0 type can' without any configuration data can_validate() tries to validate the content without taking into account that there's totally no content. This patch adds a check for missing content. Reported-by:
