While the patch does indeed fix the issue, it does it mostly by accident. To
add insult to injury it also has two style issues, all within 4 lines of code.
Seriously, if you're not sure about something, please discuss on IRC or give

The issue here is inside netlink_status_cb:
ofono_modem_set_data(isi->modem, isi);
ofono_modem_set_powered(isi->modem, TRUE);
ofono_modem_register(isi->modem);
You should not ofono_modem_set_powered a modem before registering it. The
fact that this works is pure luck.
I've reverted the patch and made a series of small fixes that should solve the
issue. I also suggest you guys use proper 'Powered' semantics and don't bring
up the device automatically. ConnMan will most likely end up managing the
'powered' user preferences store...
