ipheth_sndbulk_callback() can submit carrier_work as a part of its error handling. That means that the driver must make sure that the work is cancelled after it has made sure that no more URB can terminate with an error condition. Hence the order of actions in ipeth_close() needs to be inverted. Signed-off-by: Oliver Neukum <oneukum@suse.com> --- drivers/net/usb/ipheth.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
