DECNET: dn_nl_deladdr() almost always returns no error
[DECNET]: dn_nl_deladdr() almost always returns no error
[ Upstream commit: 3ccd86241b277249d5ac08e91eddfade47184520 ]
As far as I see from the err variable initialization
the dn_nl_deladdr() routine was designed to report errors
like "EADDRNOTAVAIL" and probaby "ENODEV".
But the code sets this err to 0 after the first nlmsg_parse
and goes on, returning this 0 in any case.
