From 4921445c17d05d41a81fc6bf92367ca6737a18f7 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Fri, 5 Oct 2012 10:41:04 +0000 Subject: [PATCH] drivers/net/ethernet/natsemi/natsemi.c: fix error return code The function natsemi_probe1() return 0 for success and negative value for most of its internal tests failures. There is one exception that is error case going to err_create_file:. Fore this error case the function abort its success execution path, but returns non negative value, making it difficult for a caller function to notice the error. This patch fixes the error case that do not return negative value. This was found by Coccinelle, but the code change was made by hand. This patch is not robot generated. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Peter Senna Tschudin Acked-by: Francois Romieu Signed-off-by: David S.
