This is dev_attr_show() calling attr->show() which points to
'part_attr_group' struct instead of a function. :-)
I'm pretty sure the following changeset is to blame:

Driver core: convert block from raw kobjects to core devices
This moves the block devices to /sys/class/block. It will create a
flat list of all block devices, with the disks and partitions in one
directory. For compatibility /sys/block is created and contains symlinks
to the disks.
