   5 Subject: isdn: isdn_tty: fix build warning of strncpy
   6
   7 From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
   8
   9 Not upstream as isdn is long deleted.
  10
  11 Fix up a strncpy build warning for isdn_tty_suspend() using strscpy.
  12
  13 It's not like anyone uses this code anyway, and this gets rid of a build
  14 warnings so that we can see real warnings as they pop up over time.
