From 502f159c0239863deebfc50e09c0892d0c157101 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 3 Jun 2015 14:52:59 +1000 Subject: [PATCH] powerpc/eeh: Fix trivial error in eeh_restore_dev_state() Commit 28158cd "powerpc/eeh: Enhance pcibios_set_pcie_reset_state()" introduced a fix for a problem where certain configurations could lead to pci_reset_function() destroying the state of PCI devices other than the one specified. Unfortunately, the fix has a trivial bug - it calls pci_save_state() again, when it should be calling pci_restore_state(). This corrects the problem.
