From 1359f2701b96abd9bb69c1273fb995a093b6409a Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Mon, 20 Oct 2008 17:40:42 -0600 Subject: PCI Hotplug core: add 'name' param pci_hp_register interface Update pci_hp_register() to take a const char *name parameter. The motivation for this is to clean up the individual hotplug drivers so that each one does not have to manage its own name. The PCI core should be the place where we manage the name. We update the interface and all callsites first, in a "no functional change" manner, and clean up the drivers later.

Update the sn_hp_slot_private_alloc() interface to fill in the correct name for us, as that function already has all the parameters needed to determine the name.
