This is caused by the wiphy may be NULL for some reason. It's likely a bug in mwifiex. We've already pinged Marvell and Murata. Before there's a real fix available, we should check wiphy before accessing it. I've tried a 4.13-rc6 kernel. Though it has oops for NULL pointer deference too, it happens in a different function in mwifiex. Thus the workaround for Xenial may or may not help for other series. Will need to reproduce this issue with Zesty and then we can decide whether this workaround should be applied to Zesty.
