From e9a7f8c5865d877e96f19dc7e6c457e42d05c030 Mon Sep 17 00:00:00 2001 From: Vaibhav Gupta Date: Wed, 1 Jul 2020 22:20:53 +0530 Subject: benet: use generic power management With legacy PM, drivers themselves were responsible for managing the device's power states and takes care of register states. After upgrading to the generic structure, PCI core will take care of required tasks and drivers should do only device-specific operations. Thus, there is no need to call the PCI helper functions like pci_enable/disable_device(), pci_save/restore_sate() and pci_set_power_state(). Compile-tested only.
