Date: Mon, 17 Sep 2012 20:05:33 +0200 From: Peter Senna Tschudin <peter.senna@...il.com> To: linux-scsi@...r.kernel.org Cc: target-devel@...r.kernel.org, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, Peter Senna Tschudin <peter.senna@...il.com> Subject: [PATCH] drivers/target/target_core_configfs.c: fix error return code From: Peter Senna Tschudin <peter.senna@...il.com> Convert a nonnegative error return code 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/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@...il.com> --- drivers/target/target_core_configfs.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/target/target_core_configfs.c b/drivers/target/target_core_configfs.c index a1b4171..015f5be 100644 --- a/drivers/target/target_core_configfs.c +++ b/drivers/target/target_core_configfs.c @@ -3124,6 +3124,7 @@ static int __init target_core_init_configfs(void) GFP_KERNEL); if (!target_cg->default_groups) { pr_err("Unable to allocate target_cg->default_groups\n"); + ret = -ENOMEM; goto out_global; } @@ -3139,6 +3140,7 @@ static int __init target_core_init_configfs(void) GFP_KERNEL); if (!hba_cg->default_groups) { pr_err("Unable to allocate hba_cg->default_groups\n"); + ret = -ENOMEM; goto out_global; } config_group_init_type_name(&alua_group, @@ -3154,6 +3156,7 @@ static int __init target_core_init_configfs(void) GFP_KERNEL); if (!alua_cg->default_groups) { pr_err("Unable to allocate alua_cg->default_groups\n"); + ret = -ENOMEM; goto out_global; } @@ -3165,14 +3168,17 @@ static int __init target_core_init_configfs(void) * Add core/alua/lu_gps/default_lu_gp */ lu_gp = core_alua_allocate_lu_gp("default_lu_gp", 1); - if (IS_ERR(lu_gp)) + if (IS_ERR(lu_gp)) { + ret = -ENOMEM; goto out_global; + } lu_gp_cg = &alua_lu_gps_group; lu_gp_cg->default_groups = kzalloc(sizeof(struct config_group) * 2, GFP_KERNEL); if (!lu_gp_cg->default_groups) { pr_err("Unable to allocate lu_gp_cg->default_groups\n"); + ret = -ENOMEM; goto out_global; } -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
