Subject: [PATCH 5.4 230/411] PCI/PM: Fix bridge_d3_blacklist[] Elo i2 overwrite of Gigabyte X299

From: Bjorn Helgaas <bhelgaas@...gle.com>

commit 12068bb346db5776d0ec9bb4cd073f8427a1ac92 upstream.

92597f97a40b ("PCI/PM: Avoid putting Elo i2 PCIe Ports in D3cold") omitted
braces around the new Elo i2 entry, so it overwrote the existing Gigabyte
X299 entry.  Add the appropriate braces.

   2974 |   .ident = "Elo i2",
        |            ^~~~~~~~
