From 3639dbd74e2e827d544bdb28b663a44449c014e1 Mon Sep 17 00:00:00 2001 From: Xu Panda Date: Fri, 23 Dec 2022 10:42:35 +0800 Subject: power: supply: test-power: use strscpy() instead of strncpy() The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL-terminated strings.
