ChangeSet 1.2181.16.10, 2005/03/17 13:54:51-08:00, [email protected]
[PATCH] PCI Hotplug: only call ibmphp_remove_resource() if argument is not NULL
If we call ibmphp_remove_resource() with a NULL argument it will write
a warning. We can avoid this here because we already look if the argument
will be NULL before (and we ignore the return code anyway).
