From 699c1985587aad3432c5ae19801efb4186db8b7a Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Tue, 20 Aug 2013 16:41:02 +0200 Subject: PCI: Add pcibios_pm_ops for optional arch-specific hibernate functionality Platforms may want to provide architecture-specific functionality when a PCI device is doing a hibernate transition. Add a weak symbol pcibios_pm_ops that architectures can override to do so.
