From feb22b7f8e62b1b987a3a1dbad95af767a1df832 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 10 Oct 2008 22:39:32 +0200 Subject: ide: add proper PCI PM support (v2) * Keep pointer to ->init_chipset method also in struct ide_host and set it in ide_host_alloc_all(). * Add ide_pci_suspend() and ide_pci_resume() helpers (default ->suspend and ->resume implementations). * ->init_chipset can no longer be marked __devinit. * Add proper PCI PM support to IDE PCI host drivers (rz1000.c and tc86c001.c are skipped for now since they need to be converted from using ->init_hwif to use ->init_chipset instead). v2: * Cleanup CONFIG_PM #ifdef-s per akpm's suggestion.
