No, it just hides the real issue:

Please factor out descriptor parsing from ide_floppy_get_capacity()
and remove superfluous "Warning: " part of the message instead if you
want something much better.

It is also a real pain for people depending on some kind of automatic
verification of patches (infamous checkpatch.pl ;).

This is not a strict rule but in 99% cases it shows that the code could
be improved further without >80 chars lines.

Thanks.
