    No, please don't. This
    (a) changes ABI structures that are exported to user space
    (b) is unnecessary - since the problem is the _warning_, not the test.

    Just shut the warning up by either removing the test (replacing it with a
    comment about why it's unnecessary), or by adding a cast, ie

    unsigned int len = ias_opt->attribute.irda_attrib_string.len;

    if (len > IAS_MAX_STRING) {

    in case the code ever expects IAS_MAX_STRING to be shorter (or if the type
    is ever changed).
