Aleksandr Bezzubikov 7498bd6058 PCI: shpchp: Enable bridge bus mastering if MSI is enabled ... commit 48b79a1450 upstream. An SHPC may generate MSIs to notify software about slot or controller events (SHPC spec r1.0, sec 4.7). A PCI device can only generate an MSI if it has bus mastering enabled. Enable bus mastering if the bridge contains an SHPC that uses MSI for event notifications.
