The edac sysfs code is doing some crazy casting of the list of
attributes that is not necessary at all.  Instead, properly point to the
correct attribute structure in the lists, which removes the need to cast
anything and the code is now properly typesafe (as much as sysfs
attribute logic is typesafe...)

Ick, I forgot the other users like edac_pci_sysfs.c that also has this
issue, so let me go fix up this series to include that at the same time.
Sorry for the noise here...

thanks,
