The orig code will release all the resources if v4l2_device_register() failed and return 0. But what we need in this case is to return an negative error code to let the caller known we are failed. So the patch save the return value of v4l2_device_register() to 'ret' and return it when error. > > On Monday 13 May 2013 13:59:45 Wei Yongjun wrote: >> From: Wei Yongjun <yongjun_...@trendmicro.com.cn> >> >> Fix to return a negative error code from the error handling >> case instead of 0, as done elsewhere in this function. >> >> Signed-off-by: Wei Yongjun <yongjun_...@trendmicro.com.cn> >> --- >> drivers/media/pci/sta2x11/sta2x11_vip.c | 3 ++- >> 1 file changed, 2 insertions(+), 1 deletion(-) >> >> diff --git a/drivers/media/pci/sta2x11/sta2x11_vip.c >> b/drivers/media/pci/sta2x11/sta2x11_vip.c index 7005695..77edc11 100644 >> --- a/drivers/media/pci/sta2x11/sta2x11_vip.c >> +++ b/drivers/media/pci/sta2x11/sta2x11_vip.c >> @@ -1047,7 +1047,8 @@ static int sta2x11_vip_init_one(struct pci_dev *pdev, >> ret = sta2x11_vip_init_controls(vip); >> if (ret) >> goto free_mem; >> - if (v4l2_device_register(&pdev->dev, &vip->v4l2_dev)) >> + ret = v4l2_device_register(&pdev->dev, &vip->v4l2_dev); >> + if (ret) >> goto free_mem; >> >> dev_dbg(&pdev->dev, "BAR #0 at 0x%lx 0x%lx irq %d\n", -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
