From 304a0807a22852fe3095a62c24b25c4d0e16d003 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Thu, 6 Sep 2012 11:23:48 -0300 Subject: [PATCH] [media] drivers/media/usb/hdpvr/hdpvr-core.c: fix error return code 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/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Peter Senna Tschudin Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/hdpvr/hdpvr-core.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/media/usb/hdpvr/hdpvr-core.c b/drivers/media/usb/hdpvr/hdpvr-core.c index 304f43ef59e..84dc26fe80e 100644 --- a/drivers/media/usb/hdpvr/hdpvr-core.c +++ b/drivers/media/usb/hdpvr/hdpvr-core.c @@ -401,12 +401,14 @@ static int hdpvr_probe(struct usb_interface *interface, client = hdpvr_register_ir_rx_i2c(dev); if (!client) { v4l2_err(&dev->v4l2_dev, "i2c IR RX device register failed\n"); + retval = -ENODEV; goto reg_fail; } client = hdpvr_register_ir_tx_i2c(dev); if (!client) { v4l2_err(&dev->v4l2_dev, "i2c IR TX device register failed\n"); + retval = -ENODEV; goto reg_fail; } #endif -- 2.11.4.GIT
