[PATCH] PCI hotplug : Switch to pci_get_bus_and_slot instead of deprecated pci_find_slot.

[JoonwooPark]

This patch fixes these warnings:

drivers/pci/hotplug/cpqphp_pci.c:92: warning: ‘pci_find_slot’ is deprecated (declared at include/linux/pci.h:481)

Close, but you need to free the reference that you now have grabed.  As
is, this patch will cause a memory leak and cause bad things to happen
:(

Take a look at the documentation for the pci_get_bus_and_slot()
function, it's not as easy as a simple search-and-replace.

thanks,

Thank you so much for your check & advise.
This time, I've tried on ibmphp_core.c, is it OK?
