There is an error based on your RFC changes.
It locates in 7/7 net: wwan: hwsim: support NMEA port emulation.

This error could be found in netdev-bpf website --Checks --netdev/build_32bit as well.
I just rollback it to previous timer_container_of() function and it builds well.

Ouch. My bad. Thank you, Slark, for noticing and fixing it.
