Date: Thu, 6 Sep 2007 09:50:30 +0200 (CEST) From: Stefan Richter Subject: firewire: fw-ohci: ignore failure of pci_set_power_state (fix suspend regression) Fixes (papers over) "Sleep problems with kernels >= 2.6.21 on powerpc", http://lkml.org/lkml/2007/8/25/155. The issue is that the FireWire controller's pci_dev.current_state of iBook G3 and presumably older PowerBooks is still in PCI_UNKNOWN instead of PCI_D0 when the firewire driver's .suspend method is called. Like it was suggested earlier in http://lkml.org/lkml/2006/10/24/13, we do not fail .suspend anymore if pci_set_power_state failed.
