+Subject: isdn: isdn_tty: fix build warning of strncpy
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+Not upstream as isdn is long deleted.
+
+Fix up a strncpy build warning for isdn_tty_suspend() using strscpy.
+
+It's not like anyone uses this code anyway, and this gets rid of a build
+warnings so that we can see real warnings as they pop up over time.
