From 1229533a2a9cd85fb18a95841e986fca79dece86 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Sat, 10 Oct 2020 10:28:04 +0200 Subject: env: split env_import_redund() into 2 functions split from env_import_redund() the part which checks which Environment is valid into a separate function called env_check_redund() and call it from env_import_redund(). So env_check_redund() can be used from places which also need to do this checks.
