From: Karel Zak Date: Thu, 14 May 2026 10:06:12 +0000 (+0200) Subject: agetty: move usage() and parse_args() before main() X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=87935d6ee8493554804e3835f4ee69beeb67d105;p=thirdparty%2Futil-linux.git agetty: move usage() and parse_args() before main() Reorder functions so that output_version(), usage() and parse_args() appear before main(), matching the convention used across the project. Remove the now unnecessary forward declarations for these functions.
