[PATCH 16/17] net2280: Move ASSERT_OUT_NAKING into out_flush

From: Ricardo Ribalda Delgado
Date: Fri Nov 28 2014 - 08:52:07 EST


ASSERT_OUT_NAKING was only called by out_flush and was hidden behind a
ifdef.

This patch moves the inline function into out_flush and remove the
ifdef. The user can decide to print the debug message or not via dynamic
printk
