[PATCH] pci/hotplug/pnv-php: Remove probable double put

[Bjorn Helgaas]

Make your subject line follow the previous convention.

Figure out if this is a "probable" or a real double put.  If it's a
real double put, we should fix it.  If it's only "probable," that
means we don't understand the problem yet.
