Subject: [PATCH next-queue v6 1/4] Revert "PCI: Make pci_enable_ptm() private"
Make pci_enable_ptm() accessible from the drivers.
Exposing this to the driver enables the driver to use the
'ptm_enabled' field of 'pci_dev' to check if PTM is enabled or not.
This reverts commit ac6c26da29c1 ("PCI: Make pci_enable_ptm() private").
