Subject: [PATCH v4 18/29] scsi: pm_8001: Drop PCI Wakeup calls from .resume
Date:   Mon,  2 Nov 2020 22:17:19 +0530

The driver calls pci_enable_wake(...., false) in pm8001_pci_resume(), and
there is no corresponding pci_enable_wake(...., true) in
pm8001_pci_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
pm8001_pci__resume().
