So you are objecting to the fact that some people are spending their own
time cleaning up this driver, which is only enabled for the devices that
are not supported by any other Linux wireless driver, because the
original developers never took the time to do the cleaning up
themselves?

Why do you want to tell others how to spend their time, when they are
trying to get devices to work properly with Linux that otherwise would
not?

So you think that the staging tree is pulling away developer help for
the other "proper" kernel drivers?

Was there supposed to be some?

I sure discussed it, as I have hardware here that needs it, yet trying
to get it working in the in-kernel driver was pretty much impossible.
So I added the staging driver and lots of users are now happy that Linux
works on their hardware and they don't have to go download some random
driver to get it to work.

I agree, and don't see how this is a problem.

Yes, these drivers are going to take a lot of work to get into "proper"
mergable shape.  But that's the whole point of the staging tree!  To do
this work, in the kernel, with lots of other developers, all the while
letting real people use their hardware with Linux today.
