net/irda: remove pointless assignment/check
We've already set sk to sock->sk and dereferenced it, so if it's NULL we would have crashed already. Moreover, if it was NULL we would have crashed anyway when jumping to 'out' and trying to unlock the sock. Furthermore, if we had assigned a different value to 'sk' we would have been calling lock_sock() and release_sock() on different sockets. My conclusion is that these two lines are complete nonsense and only serve to confuse the reader. Signed-off-by: Vegard Nossum <vegard.nossum@oracle.com> Signed-off-by: David S.
