From 20ac75e563d09f56fb00caa25a3afdb88573472d Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 18 Feb 2016 13:50:45 +0100 Subject: [PATCH] PCI/AER: Fix aer_inject error codes EPERM means "Operation not permitted", which doesn't reflect the lack of support for AER. EPROTONOSUPPORT (Protocol not supported) is a better choice of error code if the device or its root port lack support for AER. Likewise, EINVAL means "Invalid argument", which is not suitable for cases where the AER error device is missing or unusable. ENODEV and EPROTONOSUPPORT, respectively, fit better.
