The patch titled
Use WARN() in drivers/base/
has been removed from the -mm tree. Its filename was
use-warn-in-drivers-base.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: Use WARN() in drivers/base/
From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx>
Use WARN() instead of a printk+WARN_ON() pair; this way the message
becomes part of the warning section for better reporting/collection.
