D'oh. Okay, here's v2, should fix that buglet too.
This hack was used when the imon driver was using internal key lookup
routines, but became dead weight when the driver was converted to use
ir-core's key lookup routines. These bits simply didn't get removed,
drop 'em now.
Pointed out by Dan Carpenter.
v2: fix possible attempt to access beyond end of key table array,
also pointed out by Dan.
