+Subject: [PATCH] network: remove redunant link name in message
+
+Fixes #12454.
+
+gcc was complaining that the link->ifname argument is NULL. Adding
+assert(link->ifname) right before the call has no effect. It seems that
+gcc is confused by the fact that log_link_warning_errno() internally
+calls log_object(), with link->ifname passed as the object. log_object()
+is also a macro and is does a check whether the passed object is NULL.
+So we have a check if something is NULL right next an unconditional use
+of it where it cannot be NULL. I think it's a bug in gcc.
+
+Anyway, we don't need to use link->ifname here. log_object() already prepends
+the object name to the message.
