2020-05-30net: dsa: sja1105: suppress -Wmissing-prototypes in sja1105_static_config.cVladimir Oltean2-18/+18
Newer compilers complain with W=1 builds that there are non-static functions defined in sja1105_static_config.c that don't have a prototype, because their prototype is defined in sja1105.h which this translation unit does not include. I don't entirely understand what is the point of these warnings, since in principle there's nothing wrong with that. But let's move the prototypes to a header file that _is_ included by sja1105_static_config.c, since that will make these warnings go away.
