I totally agree, just kill it.  For the record this got added in:

commit 5b40964eadea40509d353318d2c82e8b7bf5e8a5
Author: Samuel Ortiz <samuel at sortiz.org>
Date:   Mon Oct 11 00:46:51 2010 +0200

    irda: Remove BKL instances from af_irda.c

which claims to be just a locking change, but obviously added
this bogus ->disconnect() call as well.
