From 94688cf2454986309fbcd495233ba2423786a14a Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Wed, 7 Nov 2007 15:43:59 -0600 Subject: PCI: export pci_restore_msi_state() PCI error recovery usually involves the PCI adapter being reset. If the device is using MSI, the reset will cause the MSI state to be lost; the device driver needs to restore the MSI state. The pci_restore_msi_state() routine is currently protected by CONFIG_PM; remove this, and also export the symbol, so that it can be used in a modle.
