The vio_remove() function uses device_find_child() but it does not drop the reference of the retrieved child. Signed-off-by: Federico Vaga <federico.vaga@xxxxxxxxx> --- I do not have a SPARC system (and I do not know it), so I cannot test this patch. Please test it. If I'm right, the device_unregister() does not work properly because, device_find_child() did get_device() on dev. In essence, the release method associated to the device will never be invoked because there is a reference to the device that is not dropped. arch/sparc/kernel/vio.c | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/sparc/kernel/vio.c b/arch/sparc/kernel/vio.c index 3e244f3..8647fcc 100644 --- a/arch/sparc/kernel/vio.c +++ b/arch/sparc/kernel/vio.c @@ -342,6 +342,7 @@ static void vio_remove(struct mdesc_handle *hp, u64 node) printk(KERN_INFO "VIO: Removing device %s\n", dev_name(dev)); device_unregister(dev); + put_device(dev); } } -- 1.8.1.4 -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
