+From ddf634b92bf96b35f521db6da329628b4525c2eb Mon Sep 17 00:00:00 2001
+From: Sven Schwermer <sven.schwermer@disruptive-technologies.com>

+Subject: [PATCH 2/2] fcc-unlock: Make scripts POSIX shell compatible
+
+This allows us to not rely on bash which may not be available on
+constrained systems, e.g. Yocto-built embedded systems. The scripts now
+pass shellcheck.
