From 20d4369b6892159895d6136946e692eaf29e8413 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 11 Jan 2012 23:55:04 +0000 Subject: drivers/net/ethernet/tundra/tsi108_eth.c: add missing iounmap Add missing iounmap in error handling code, in a case where the function already preforms iounmap on some other execution path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression e; statement S,S1; int ret; @@ e = \(ioremap\|ioremap_nocache\)(...) ... when != iounmap(e) if (<+...e...+>) S ... when any when != iounmap(e) *if (...) { ... when != iounmap(e) return ...; } ... when any iounmap(e); // Signed-off-by: Julia Lawall Signed-off-by: David S.
