commitef222f551eupstream. While performing certain power-off sequences, PCI drivers are called to suspend and resume their underlying devices through PCI PM (power management) interface. However the hardware does not support PCI PM suspend/resume operations so system wide suspend/resume leads to bad MFW (management firmware) state which causes various follow-up errors in driver when communicating with the device/firmware. To fix this driver implements PCI PM suspend handler to indicate unsupported operation to the PCI subsystem explicitly, thus avoiding system to go into suspended/standby mode.
