From 1f2fd14997b38b8aeeaae5de8f81c3a04958971e Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Wed, 24 Aug 2011 05:40:10 +0100 Subject: keyspan_pda: Fix parse error with as31 version 2.3.1 keyspan_pda.S has an out-of-range decimal constant that looks like it was really meant to be a binary constant. Comparing with the binary, it appears that as31 used to treat this as 0, so change the source to use 0 and add a comment on this.
