+
+Some PCIe devices do not support LOS, and will cause timeouts if the
+root complex forces the LOS state. This patch disables the LOS state
+by default.
+
+This is part of fixing bug
+https://bugzilla.kernel.org/show_bug.cgi?id=196339, this commit was
+reported as the user to be important to get a Intel 7260 mini-PCIe
+WiFi card working.
+
+Fixes: 8c39d710363c1 ("PCI: aardvark: Add Aardvark PCI host controller driver")
