+Subject: [PATCH] MIPS: BCM47XX: Add Luxul XAP1500/XWR1750 WiFi LEDs
+
+Some Luxul devices use PCIe connected GPIO LEDs that are not available
+until the PCI subsytem and its drivers load. Using the same array for
+these LEDs would block registering any LEDs until all GPIOs become
+available. This may be undesired behavior as some LEDs should be
+available as early as possible (e.g. system status LED). This patch will
+allow registering available LEDs while deferring these PCIe GPIO
+connected 'extra' LEDs until they become available.
