Subject: [Linux-kernel-mentees] [PATCH v3 24/28] scsi: mvumi: Drop PCI Wakeup calls from .resume
Date: Thu,  1 Oct 2020 17:55:07 +0530	[thread overview]
Message-ID: <20201001122511.1075420-25-vaibhavgupta40@gmail.com> (raw)
In-Reply-To: <20201001122511.1075420-1-vaibhavgupta40@gmail.com>

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