From 9d1f8a40ddab65a5cedb69b369ee4c0c6e4acf6b Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Sat, 22 Jan 2011 20:55:39 +0100 Subject: hwmon: (applesmc) Properly initialize lockdep attributes The switch to dynamically allocated sysfs attributes left the internal lockdep members uninitialized, causing a formal bug. This patch adds sysfs_attr_init() to the node creation function, remedying the problem.

Add a DMI entry to override the detection heuristic and force the use of the "new" interface on this board.
