From 671646c151d492c3846e6e6797e72ff757b5d65e Mon Sep 17 00:00:00 2001 From: Kai-Heng Feng Date: Thu, 21 Jun 2018 16:30:38 +0800 Subject: [PATCH] r8169: Don't disable ASPM in the driver Enable or disable ASPM should be done in PCI core instead of in the device driver. Commit ba04c7c93bbc ("r8169: disable ASPM") uses pci_disable_link_state() to disable ASPM, but it's not the best way to do it. If the device really wants to disable ASPM, we can use a quirk in PCI core to prevent the PCI core from setting ASPM before probe. Let's remove pci_disable_link_state() for now. Use PCI core quirks if any regression happens. Signed-off-by: Kai-Heng Feng Signed-off-by: David S.
