From 080ba929651a32f1840751d2b862e64c8ee1f0c6 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 6 Jan 2009 14:41:25 -0800 Subject: checkpatch: try to catch missing VMLINUX_SYMBOL() in vmlinux.lds.h Seems like every other release we have someone who updates vmlinux.lds.h and adds C-visible symbols without VMLINUX_SYMBOL() around them. So start checking the file and reject assignments which have plain symbols on either side.
