Hallo Valentin,
thanks for the idea for the cleanup.
But if you replace the the printk() statements it's worth to check if code
fits into a single line now, e.g.

As i've seen in former patches from Joe Perches OOM messages are obsolete.
You could write
if(!d)
return NOTIFY_DONE;
here instead.
Thanks,
Oliver

While at it, why not switch to dev_err() instead?

Hm, no.
1. pr_err() would be fine, as dev_err() is for drivers - and we're in
linux/net here and not in linux/drivers
2. When removing the entire printk() statement there's nothing to be modified left

Oliver
