[Linux-kernel-mentees] [PATCH v3 20/28] scsi: 3w-9xxx: Drop PCI Wakeup calls from .resume

The driver calls pci_enable_wake(...., false) in twa_resume(), and
there is no corresponding pci_enable_wake(...., true) in twa_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
