pull-request: ieee802154-next 2026-06-20

[Stefan Schmidt <stefan@datenfreihafen.org>]

Hello Dave, Jakub, Paolo.

An overdue pull request for ieee802154, catching up on all the AI found issues
at last.

Shitalkumar Gandhi fixed problems in the ca8210 driver for cases where we could
have a leak or a pointer truncation.

Robertus Diawan Chris made sure we do not overwrite the return code when
associating.

Michael Bommarito worked on properly gating our netlink API use in the llsec
security context.

Ivan Abramov cleaned up the netns cases as he did in other subsystems.

Doruk Tan Ozturk ensures we have the correct skn ready in cryptoo operation (to
avoid a  silent overwrite).

Aleksandr Nogikh fixed a kernel-infoleak detected by syzbot.

regards
Stefan Schmidt
