Merge patch series "can: j1939: resend lost patches for buffer init and netdevice tracking"

Browse source

Oleksij Rempel <o.rempel@pengutronix.de> says:

This series collects and resends two j1939 patches that were previously
lost on their way upstream. They address different, unconnected issues in
the stack:

- Patch 1 prevents residual data leaks by zeroing the allocated receive
  buffer in j1939_session_fresh_new().
- Patch 2 implements netdevice_tracker for j1939_{priv,session,ecu}
  management to help investigate a dev_hold()/dev_put() refcount
  leak (unregister_netdevice() waiting for vcan0) reported by syzbot.
