[PATCH 6/8] net: sched: use IS_ENABLED() instead of checking for built-in or module

From: Javier Martinez Canillas
Date: Fri Sep 09 2016 - 08:44:49 EST


The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.
