The main motivation for this patch is that for the first strncmp()
we do 'strncmp(src, "-", 20)' but "src" is a 15 character buffer not 20.
Also since we know that "-" is only two characters, the compare isn't
going to go further than 2 characters into src before deciding that it
doesn't match.
The same applies to the other strncmp()s. In those cases "str" is
actually 10 characters so the limiter is correct but it is still not
needed when the length for "adapter" and "firmware" is known and less
than 10.
