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).
