[PATCH 4.9 06/96] isdn: isdn_tty: fix build warning of strncpy

From: Greg Kroah-Hartman
Date: Tue Mar 12 2019 - 13:22:24 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

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.
