At first this was plain warning without code removal but I've
been advised that dropping it completely may be a better idea
which I agree https://lkml.org/lkml/2018/4/4/31 Or you mean the
warning message itsef? We aready have similars, for example
in kernel/auditfilter.c

printk(KERN_ERR "AUDIT_POSSIBLE is deprecated\n");
