Ah. I'd buy that. I like readability fixes. The indenting is also
messed up and confusing. It should be:

if (check_fwstate(pmlmepriv, _FW_LINKED | WIFI_ADHOC_MASTER_STATE |
WIFI_AP_STATE))
memcpy(wrqu->ap_addr.sa_data, pcur_bss->MacAddress, ETH_ALEN);
else
memset(wrqu->ap_addr.sa_data, 0, ETH_ALEN);
