From 1d0243559497b9cab00099c49a5ba3222cd6576f Mon Sep 17 00:00:00 2001 From: Andrew Patterson Date: Mon, 12 Oct 2009 13:14:10 -0600 Subject: [PATCH] PCI: use better error return values in aer_inject Replaced some error return values in aer_inject. Use -ENODEV when we can't find a device and -ENOTTY when the device does not support PCIe AER.
