> I wonder if you could just memset this whole array to 0?  or is the dev check important?

Good suggestion.  Given this logic never set it to 1, only to 0, whether or not dev is enabled isn't really important here (original logic in soc set to 1 or 0, so it was important that it made sure dev was active before setting to 1, but the new logic doesn't need it).
