driver-core: Add attribute argument to class_attribute show/store
Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
