From: Peter Senna Tschudin <peter.senna@xxxxxxxxx> 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@xxxxxxxxx> --- drivers/mmc/host/dw_mmc.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/mmc/host/dw_mmc.c b/drivers/mmc/host/dw_mmc.c index 36f98c0..43a2663 100644 --- a/drivers/mmc/host/dw_mmc.c +++ b/drivers/mmc/host/dw_mmc.c @@ -2039,8 +2039,10 @@ int dw_mci_probe(struct dw_mci *host) tasklet_init(&host->tasklet, dw_mci_tasklet_func, (unsigned long)host); host->card_workqueue = alloc_workqueue("dw-mci-card", WQ_MEM_RECLAIM | WQ_NON_REENTRANT, 1); - if (!host->card_workqueue) + if (!host->card_workqueue) { + ret = -ENOMEM; goto err_dmaunmap; + } INIT_WORK(&host->card_work, dw_mci_work_routine_card); ret = request_irq(host->irq, dw_mci_interrupt, host->irq_flags, "dw-mci", host); if (ret) -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
