Please add here the testing you did.

That should be all.  You might want to get acquinted with the checkpatch
script, it would have pointed the "else" thing to you, I think (I didn't

Anyway, other than the cosmetic stuff above, the patch looks good.  I
haven't tested it yet on a IBM thinkpad, though.  Will do later today.
