However,\nPCI core handles all this on behalf of the driver. Furthermore with PTM\nenabled the PCI core re-enables it on resume but the driver calls\npci_restore_state() which ends up disabling it again.\n\nFor this reason let the PCI core handle the common PM resume flow.\n\nSigned-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>\nReviewed-by: Andy Shevchenko <andriy.shevchenko@intel.com>\nAcked-by: Vinicius Costa Gomes <vinicius.gomes@intel.com>\nReviewed-by: Jacob Keller <jacob.e.keller@intel.com>\nTested-by: Avigail Dahan <avigailx.dahan@intel.com>\nSigned-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>\n---\n drivers/net/ethernet/intel/igc/igc_main.c | 6 ------\n 1 file changed, 6 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/igc/igc_main.c b/drivers/net/ethernet/intel/igc/igc_main.c\nindex 98024b46789f..0e785af0a3a3 100644\n--- a/drivers/net/ethernet/intel/igc/igc_main.c\n+++ b/drivers/net/ethernet/intel/igc/igc_main.c\n@@ -7544,9 +7544,6 @@ static int __igc_resume(struct device *dev)\n \tstruct igc_hw *hw = &adapter->hw;\n \tu32 err, val;\n \n-\tpci_set_power_state(pdev, PCI_D0);\n-\tpci_restore_state(pdev);\n-\n \tif (!pci_device_is_present(pdev))\n \t\treturn -ENODEV;\n \terr = pci_enable_device_mem(pdev);\n@@ -7556,9 +7553,6 @@ static int __igc_resume(struct device *dev)\n \t}\n \tpci_set_master(pdev);\n \n-\tpci_enable_wake(pdev, PCI_D3hot, 0);\n-\tpci_enable_wake(pdev, PCI_D3cold, 0);\n-\n \tif (igc_is_device_id_i226(hw))\n \t\tpci_disable_link_state(pdev, PCIE_LINK_STATE_L1_2);\n \n", "prefixes": [ "net-next", "02/15" ] }
