Yes, that is fine. Anyway, there are no ABI issues inside wpa_supplicant
because there is no requirement on interfaces/structures being _binary_
compatible, i.e., it is acceptable to change structures as long as
recompilation is enough and source level compatibility is maintained on
"supported interfaces" (which is not very well defined, but includes at
least the driver, TLS/crypto, l2_packet, and ctrl_iface backend
interfaces).

Thanks! Applied with some cleanup and couple of bug fixes (always
verify that wpa_zalloc returns !=NULL before dereferencing the pointer;
do not leak memory on realloc error path).
