Commit eaf148359d009d70aec13ae3772675b25890822e upstream.
The driver calls pci_enable_wake(...., false) in scsih_resume(), and there is no corresponding pci_enable_wake(...., true) in scsih_suspend(). Either it should do enable-wake the device in .suspend() or should not invoke pci_enable_wake() at all.
Concluding that this driver doesn't support enable-wake and PCI core calls pci_enable_wake(pci_dev, PCI_D0, false) during resume, drop it from scsih_resume().
