It isn't. But the disconnect is still wrong. You fail to unlink the current
urb. This has to be done before you kill the tasklet. And you have to use a
flag and a spinlock to guard against a race with the completion handler.
There's a recent discussion on this in the usb archives. And you need to
defer freeing the memory if the device is open.
Have a look at how pwc does it. It should be correct in that regard.
And while you at it, could you rename the tasklet from ...bh... to ...tl... ?
It's no longer a bottom half.
