Revision 834145156bedadfb50121f0bc5e9d9f9f942bcca authored by Rafael J. Wysocki on 14 September 2013, 01:38:20 UTC, committed by Rafael J. Wysocki on 19 September 2013, 22:24:43 UTC
Commit 448bd85 (PCI/PM: add PCIe runtime D3cold support) added a piece of code to pci_acpi_wake_dev() causing that function to behave in a special way for devices in D3cold (so that their configuration registers are not accessed before those devices are resumed). However, it didn't take the clearing of the pme_poll flag into account. That has to be done for all devices, even if they are in D3cold, or pci_pme_list_scan() will not know that wakeup has been signaled for the device and will poll its PME Status bit unnecessarily. Fix the problem by moving the clearing of the pme_poll flag in pci_acpi_wake_dev() before the code introduced by commit 448bd85. Reported-and-tested-by: David E.
