From 0d465f23502e0810443c90a9cf1cf5686c4af4f2 Mon Sep 17 00:00:00 2001 From: Hidetoshi Seto Date: Mon, 7 Sep 2009 17:10:40 +0900 Subject: PCI: pcie, aer: fix report of multiple errors The flag AER_MULTI_ERROR_VALID_FLAG in info->flag does mean that the root port receives multiple error messages. Error messages can be posted from different devices, so it does not mean that each reported device has multiple errors. If there are multiple error devices and the root port has valid error source ID, it would be nice to report which device is the error source reported first.
