[PATCH -v7 3/4] PCI, do not call pci_set_power_state with PCI_D3cold

From: Huang Ying
Date: Fri Jun 22 2012 - 22:25:30 EST


PCI subsystem has not been ready for D3cold support yet. So
PCI_D3cold should not be used as parameter for pci_set_power_state.
This patch is needed for upcoming PCI_D3cold support.

This patch has no functionality change, because pci_set_power_state
will bound the parameter to PCI_D3hot too.
