Subject: [patch] applicom: use correct array offset
Date: Fri, 1 Mar 2013 23:31:46 +0300	[thread overview]
Message-ID: <20130301203146.GC22066@longonot.mountain> (raw)

We're iterating through abps[] printing information, but here we
use the wrong array index.  IndexCard comes from the user and in
this case it was specifically not range checked because we didn't
expect to use it.
