Arend van Spriel db4efbbeb4 brcmfmac: obtain platform data upon module initialization ... The driver uses platform_driver_probe() to obtain platform data if any. However, that function is placed in the .init section so it must be called upon driver module initialization. The problem was reported by Fenguang Wu resulting in a kernel oops because the .init section was already freed.
