The function ieee802154_iface_init() references
the variable __init .L0 .
This is often because ieee802154_iface_init lacks a __init
annotation or the annotation of .L0 is wrong.

I freely confess that I have no idea what any of these error messages
are trying to tell me. What is ".init.txt.L0"? How did my patch affect
ieee802154_iface_init() or the register_netdevice_notifier() function
that it invokes? For that matter, how did my patch cause an access to
be made to __init data from a non-__init function?
Thanx, Paul

Hi Paul,

The problem has existed for some time before your patch, we'll add it to
ignore list to avoid noise.

Thank you for getting back to me.
Very well, I will ignore subsequent errors that look like this. ;-)
