From: Julia Lawall <julia.law...@lip6.fr> 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.law...@lip6.fr> --- Not tested. drivers/char/xilinx_hwicap/xilinx_hwicap.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/char/xilinx_hwicap/xilinx_hwicap.c b/drivers/char/xilinx_hwicap/xilinx_hwicap.c index f6345f9..9b1a5ac 100644 --- a/drivers/char/xilinx_hwicap/xilinx_hwicap.c +++ b/drivers/char/xilinx_hwicap/xilinx_hwicap.c @@ -661,6 +661,7 @@ static int hwicap_setup(struct device *dev, int id, drvdata->base_address = ioremap(drvdata->mem_start, drvdata->mem_size); if (!drvdata->base_address) { dev_err(dev, "ioremap() failed\n"); + retval = -ENOMEM; goto failed2; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
