I suspect you could simplify this a bit by doing something like:
const unsigned int *intbuf;
if (IS_V4(inst->core)) {
arr_sz = ARRAY_SIZE(intbuf_types_4xx);
intbuf = intbuf_types_4xx;
} else {
arr_sz = ARRAY_SIZE(intbuf_types_1xx);
intbuf = intbuf_types_1xx;
}
for (i = 0; i < arr_sz; i++) {
ret = intbufs_set_buffer(inst, intbuf[i]);
if (ret)
goto error;

These structures are being used in the next patch - wouldn't it make
more sense to move their declaration there as well?
