We recently had a patch that fixes this, among more leaks. Subject:
[PATCH v2 resend] b43: Fix memory leaks in b43_bus_dev_ssb_init and
b43_bus_dev_bcma_init

Please test that patch instead, so we can finally apply it.

It needs to be tested on both ssb and bcma. Come on. This isn't too
hard. :) Please somebody with any hardware test it. (I currently don't
have any b43 hardware)
