igb: call pci_save_state after pci_restore_state
Nick Nunley [Wed, 17 Feb 2010 01:02:19 +0000 (01:02 +0000)]
This patch adds calls to pci_save_state() immediately after
calls to pci_restore_state(). Due to a change in the behavior
of pci_restore_state() it is necessary to call pci_save_state()
to keep the state_saved flag. This patch is based on a similar
patch for ixgbe.
