netrom: fix copying in user data in nr_setsockopt
This code used to copy in an unsigned long worth of data before the sockptr_t conversion, so restore that. Fixes: a7b75c5a8c41 ("net: pass a sockptr_t into ->setsockopt") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S.
