commit 82ce251d5c7d9c310e55314ebb943aa61c48bc89 Author: Patrick Rudolph siro@das-labor.org Date: Sat Feb 6 13:03:21 2016 +0100
southbridge/intel/bd82x6x/acpi: Fix IRQ warnings
The PCIe slot uses Message Signaled Interrupts (MSI) as the IGD does and doesn't use hardware INT lines. Adding the IRQ entry for PEG slot fixes a warning showing up in GNU/Linux dmesg.
Test system: * Intel IvyBridge * Gigabyte GA-B75M-D3H
