Hi stable team,

Could you please consider backporting upstream commit

9e7f36ab5b7bf68463faa5f7b926fea8f35597bb
("net: appletalk: fix NULL pointer dereference in aarp_send_ddp()")

for 6.18.y, 6.12.y, 6.6.y, 6.1.y, 5.15.y, and 5.10.y.

It fixes a NULL pointer dereference when sending through a device
without an AppleTalk interface configured.

The fix has been in mainline since May 18 but is still absent from the
longterm branches.

The upstream commit applies cleanly to all of these branches.

Thanks,
Xiang

Now queued up.  Note, this is deleted in newer kernels.
