From 5a4910fbbeef14cc91daa41086449a1a4acebc96 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Tue, 27 Feb 2007 09:14:58 +0100 Subject: kbuild: whitelist logo references from .text to .init.data drivers/video/logo has references from .text to .init.data but function is only used during early init. So reference is OK and we do not want to warn about them => whitelist the reference.
