From 609d8536cd125793fe52b393e854dd7df238c954 Mon Sep 17 00:00:00 2001
From: Frans Meulenbroeks <fransmeulenbroeks@gmail.com>

Subject: [PATCH 1/5] cmd_i2c.c: reduced subaddress length to 3 bytes
according to some of the comments the subaddress length is 1 or 2, but we are being
prepared for the case it becomes 3. However the code also accepted 4.
This repairs this by changing the constand 4 to 3.
