From e5a98fc25a4f688f01b073d9fe0bbccc7807ab8e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 7 Aug 2014 15:31:05 +0200 Subject: drivers/atm/atmtcp.c: fix error return code Convert a zero return value on error to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Julia Lawall Acked-by: Chas Williams Signed-off-by: David S.
