I am trying to modify an existing device driver to build with Debian 220.127.116.11 as a target. The driver is one we downloaded and is a couple of years old so pre-dates 18.104.22.168. It wants to invoke a macro/function called "info", e.g. info(DRIVER_VERSION ":" DRIVER_DESC);. This macro/function cannot be found in the build environment and I cannot find any information on it. Does anyone know what/where this is?
