For data types which are known to be terminal, const more or less works, I suppose but for anything even mildly complicated it ends up being more of a headache. C just doesn't have enough language support to make const actually useful. e.g. now if somebody wants to add an accessor to ahci_platform_data() which is applicable to both readers and writers, we either need two separate accessors for const and !const paths or have to cast away const.
