From: Julia Lawall <Julia.Lawall@xxxxxxx> Set the return variable to an error code as done 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: Julia Lawall <Julia.Lawall@xxxxxxx> --- Not tested. drivers/mtd/ubi/attach.c | 4 +++- drivers/mtd/ubi/build.c | 4 +++- 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/mtd/ubi/attach.c b/drivers/mtd/ubi/attach.c index 33bb1f2..6f27d9a 100644 --- a/drivers/mtd/ubi/attach.c +++ b/drivers/mtd/ubi/attach.c @@ -1453,8 +1453,10 @@ int ubi_attach(struct ubi_device *ubi, int force_scan) struct ubi_attach_info *scan_ai; scan_ai = alloc_ai("ubi_ckh_aeb_slab_cache"); - if (!scan_ai) + if (!scan_ai) { + err = -ENOMEM; goto out_wl; + } err = scan_all(ubi, scan_ai, 0); if (err) { diff --git a/drivers/mtd/ubi/build.c b/drivers/mtd/ubi/build.c index e05dc62..57deae9 100644 --- a/drivers/mtd/ubi/build.c +++ b/drivers/mtd/ubi/build.c @@ -1245,8 +1245,10 @@ static int __init ubi_init(void) ubi_wl_entry_slab = kmem_cache_create("ubi_wl_entry_slab", sizeof(struct ubi_wl_entry), 0, 0, NULL); - if (!ubi_wl_entry_slab) + if (!ubi_wl_entry_slab) { + err = -ENOMEM; goto out_dev_unreg; + } err = ubi_debugfs_init(); if (err) -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
