The problem is that ai_doattach() is returning NULL. I added pr_err() statements 
to each of the places that this could happen and found that the error in in this 
fragment:

         /* scan for cores */
         if (socitype == SOCI_AI) {
                 SI_MSG("Found chip type AI (0x%08x)\n", w);
                 /* pass chipc address instead of original core base */
                 ai_scan(&sii->pub, pbus);
         } else {
                 /* Found chip of unknown type */
                 pr_err("Found chip of type %d\n", socitype);
                 return NULL;
         }

This one logs "brcmsmac: Found chip of type 4". As SOC_AI is the only SOCI_XX 
that is defined, I am not sure that I will be able to get further.
