From f417f5e4ba79a08e992c79a4bb84c8a8c5062017 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 4 Sep 2010 08:33:03 +0000 Subject: isdn: cleanup: make buffer smaller This showed up in my audit because we use strcpy() to copy "ds" into a 32 character buffer inside the isdn_tty_dial() function. But it turns out that we only ever use the first 32 characters so it's OK. I have changed the declaration to make the static checkers happy. Signed-off-by: Dan Carpenter Signed-off-by: David S.
