If anyone has any objections, please let me know. ------------------ From: Mario Limonciello commit 6967741d26c87300a51b5e50d4acd104bc1a9759 upstream. When dGPU is put into BOCO it may be in D3cold but still able send PME on display hotplug event. For this to work it must be enabled as wake source from D3. When runpm is enabled use pci_wake_from_d3() to mark wakeup as enabled by default.
