Subject: [patch 7/17] use WARN() in kernel/lockdep.c

From: Arjan van de Ven <arjan@...ux.intel.com>
Subject: Use WARN instead of printk+WARN_ON in kernel/lockdep.c

Use WARN() instead of a printk+WARN_ON() pair; this way the message
becomes part of the warning section for better reporting/collection.
