[PATCH] ipw2200 locking fix
Well, this is not 100% if when the card fires two consecutive interrupts. Though unlikely, it's better to protect early than seeing some "weird" bugs one day. I proposed attached patch. If you can help to test, that will be appreciated (I cannot see the lockdep warning on my box somehow).
