From 410e78df06372507d1b836d8d825d3e3cdd11e93 Mon Sep 17 00:00:00 2001 From: Francis Laniel Date: Fri, 22 Dec 2023 22:02:37 +0100 Subject: [PATCH] test: hush: Fix variable expansion tests for modern hush Modifies the expected result for modern hush. Indeed, there were bugs in actual U-Boot hush which were fixed in upstream Busybox. As modern hush is based on upstream Busybox, these bugs no longer exist.
