Message-id: 47C5AEB5.7040302@redhat.com
O-Subject: [RHEL 5.2 PATCH 1/2] - Permits pci error state recovery
Bugzilla: 434857

  RHBZ#:
------
https://bugzilla.redhat.com/show_bug.cgi?id=434857

Overview:

Backport from mainline; initializes error_state to
pci_channel_io_normal. Without this change, the driver is essentially doing:

if (np->s.device->error_state != pci_channel_io_normal)
    return IRQ_NONE;

Subject: rhel5.2: Initialize error_state to pci_channel_io_normal

From: Mike Anderson <andmike@linux.vnet.ibm.com>

This patch is a back port from mainline to initialize error_state to
pci_channel_io_normal.
