Subject: [PATCH-next v2 3/4] net/sched: make sch_blackhole.c explicitly non-modular

From: Paul Gortmaker <[email-masked]>
Date: Wed, 7 Oct 2015 17:27:45 -0400

The Kconfig currently controlling compilation of this code is:

net/sched/Kconfig:menuconfig NET_SCHED
net/sched/Kconfig:      bool "QoS and/or fair queueing"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.  We can
change to one of the other priority initcalls (subsys?) at any later
date, if desired.

We also delete the MODULE_LICENSE tag since all that information
is already contained at the top of the file in the comments.
