hysdn: fix writing outside the field on 64 bits
ifa_local is assumed to be unsigned long which lead to writing the address at dev->dev_addr-2 instead of +2 noticed thanks to gcc: drivers/isdn/hysdn/hysdn_net.c: In function `net_open': drivers/isdn/hysdn/hysdn_net.c:91: warning: array subscript is below array bounds Signed-off-by: Pascal Terjan <pterjan@mandriva.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S.
