From 6e8e7981eb86e2c19401825dbdb55d5860d11313 Mon Sep 17 00:00:00 2001 From: Glen Choo Date: Wed, 28 Jun 2023 19:26:30 +0000 Subject: config: pass source to config_parser_event_fn_t ..so that the callback can use a "struct config_source" parameter instead of "config_reader.source". "struct config_source" is internal to config.c, so we are adding a pointer to a struct defined in config.c into a public function signature defined in config.h, but this is okay because this function has only ever been (and probably ever will be) used internally by config.c. As a result, the_reader isn't used anywhere, so "struct config_reader" is obsolete (it was only intended to be used with the_reader). Remove them.
