Subject: can: fix oops caused by wrong rtnl dellink usage

From: Oliver Hartkopp <[email protected]>

commit 25e1ed6e64f52a692ba3191c4fde650aab3ecc07 upstream.

For 'real' hardware CAN devices the netlink interface is used to set CAN specific communication parameters. Real CAN hardware can not be created nor removed with the ip tool ...

This patch adds a private dellink function for the CAN device driver interface that does just nothing.

It's a follow up to commit 993e6f2fd ("can: fix oops caused by wrong rtnl newlink usage") but for dellink.
