Subject: [PATCH v2 0/2] smsc: use generic power management

Linux Kernel Mentee: Remove Legacy Power Management.

The purpose of this patch series is to remove legacy power management callbacks
from smsc ethernet drivers.

The callbacks performing suspend() and resume() operations are still calling
pci_save_state(), pci_set_power_state(), etc. and handling the power management
themselves, which is not recommended.

The conversion requires the removal of the those function calls and change the
callback definition accordingly and make use of dev_pm_ops structure.

All patches are compile-tested only.

V2: Kbuild in V1, warning: variable 'err' is used uninitialized whenever 'if'
conditio is false in funcution .resume() .
