[PATCH] tpm: sysfs owernship changes

Browse Source 
In the current driver all sysfs files end up owned by the base driver module
rather than the module that actually owns the device this is a problem if the
module is unloaded and the file is open.  This patch fixes all that and lumps
the files into an attribute_group.
