The patch below seems to fix the problem, but a verification would be most
welcome. Gunther, do you want to take it, or should it route it through
my tree?

Thanks,
Henrik

Subject: [PATCH] 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.
