Unnecessary parentheses are removed as reported by checkpatch.pl
to make coder nicer and to improve readability.
Also coding style is improved.For example:-
It's often nicer to read if &(foo[0]) is converted to foo like:
     memcpy(&(ap->bssid[0]), &(ap_info->bssid[0]), ETH_ALEN);
     memcpy(ap->bssid, ap_info->bssid, ETH_ALEN);

Should this be a v2, or some larger number?
