'sparse' spotted that the parameters to kzalloc in l2tp_dfs_seq_open
were swapped.
Tested on current git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
at 
1792f17b7210280a3d7ff29da9614ba779cfcedb  build, boots and I can see that directory,
but there again I could see /sys/kernel/debug/l2tp with it swapped; I don't have
any l2tp in use.
