Crud...this has to be the following:
commit e6c5fc53d0f44a772398402ee8a1879818e42b4e

ipw2200: fix oops on missing firmware
For non-monitor interfaces, the syntax for alloc_ieee80211/free_80211
is wrong. Because alloc_ieee80211 only creates (wiphy_new) a wiphy, but
free_80211() does wiphy_unregister() also. This is only correct when
the later wiphy_register() is called successfully, which apparently
is not the case for your fw doesn't exist one.

Can you revert that and attempt to recreate?
