From 1d71eb53e45187f58089d32b51e27784c791d90e Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Mon, 26 Jul 2021 20:36:54 -0700 Subject: 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").
