Subject: [PATCH 1/5] Remove path attribute from sgi_hotplug

[Please note, I got Rick Jones' email screwed up in the 0/5
email; it's corrected above.]

From: Alex Chiang <achiang@...com>

Rename the slot to be the contents of the 'path' sysfs attribute, and
delete the attribute.  The mapping from pci address to slot name is
supposed to be done through the 'address' file, which will be provided
automatically later in this series of patches.
