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/block/umem.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/block/umem.c b/drivers/block/umem.c index 4cf81b5..371e819 100644 --- a/drivers/block/umem.c +++ b/drivers/block/umem.c @@ -881,6 +881,7 @@ static int mm_pci_probe(struct pci_dev *dev, const struct pci_device_id *id) if (card->mm_pages[0].desc == NULL || card->mm_pages[1].desc == NULL) { dev_printk(KERN_ERR, &card->dev->dev, "alloc failed\n"); + ret = -ENOMEM; goto failed_alloc; } reset_page(&card->mm_pages[0]); @@ -891,8 +892,10 @@ static int mm_pci_probe(struct pci_dev *dev, const struct pci_device_id *id) card->biotail = &card->bio; card->queue = blk_alloc_queue(GFP_KERNEL); - if (!card->queue) + if (!card->queue) { + ret = -ENOMEM; goto failed_alloc; + } blk_queue_make_request(card->queue, mm_make_request); card->queue->queue_lock = &card->lock; -- 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
