Subject: can: fix handling of unmodifiable configuration options fix

From: Oliver Hartkopp <[email protected]>

commit bce271f255dae8335dc4d2ee2c4531e09cc67f5a upstream.

With upstream commit bb208f144cf3f59 (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.
