+// This is a dummy module to make the firmware available when needed
+// and allows it to be unloaded when not. Rumor is the __initdata
+// macro doesn't always works on all platforms so we use this kludge.
+// If not compiled as a module it just makes fip_firm avaliable then
+// __initdata should work as advertized
