I just added the wlan-ng usb driver (and stack) to the drivers/staging/
tree a few hours ago :)

So yes, we do need to do this kind of migration, at the moment I am
trying to track down all out-of-tree drivers that distros and users are
relying on to get them into staging/ and then we can work on cleaning
them up and moving them to the proper place in the kernel tree.

Sound good?

So, for this driver, should I do the same thing, as I don't think these
devices are covered by any other driver at the moment, right?
