Subject: [patch] thermal: make lockdep happy

Hi Christian,

Can you test this patch?

I wrote this to address bugzilla bug:
	https://bugzilla.kernel.org/show_bug.cgi?id=15504
	BUG: key ffff88004c3811e0 not in .data! occured in lockdep.c

We now have to call sysfs_attr_init() for dynamically allocated sysfs 
attributes or lockdep complains.
