[PATCH] shpchp: Implement get_address callback
The following patch implements .get_address callback of hotplug_slot_ops for SHPCHP driver. With this patch, we can see bus address of hotplug slots as follows: $ cat address 0000:0b:01 Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
