From: Li Nan <linan122@xxxxxxxxxx> "if device_add() succeeds, you should call device_del() when you want to get rid of it." In sd_probe(), device_add_disk() fails when device_add() has already succeeded, so change put_device() to device_unregister() to ensure device resources are released. Fixes: 2a7a891f4c40 ("scsi: sd: Add error handling support for add_disk()") Signed-off-by: Li Nan <linan122@xxxxxxxxxx> --- drivers/scsi/sd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/scsi/sd.c b/drivers/scsi/sd.c index 542a4bbb21bc..d81cbeee06eb 100644 --- a/drivers/scsi/sd.c +++ b/drivers/scsi/sd.c @@ -3736,7 +3736,7 @@ static int sd_probe(struct device *dev)error = device_add_disk(dev, gd, NULL);if (error) { - put_device(&sdkp->disk_dev); + device_unregister(&sdkp->disk_dev); put_disk(gd); goto out; }
