commit 1d71eb53e45187f58089d32b51e27784c791d90e upstream. 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").
