[SLIP]: Simplify sl_free_bufs()
We can avoid assignments to the local variable 'tmp' and actually get rid of tmp alltogether in sl_free_bufs(). This patch does that. This is safe since both kfree() and slhc_free() handles NULL pointers gracefully. Signed-off-by: Jesper Juhl <juhl-lkml@dif.dk> Signed-off-by: David S. Miller <davem@davemloft.net>
