I know this is not really satisfying, but we normally do not do it like
this. Patches are split in one author per patch.

Please send a separate patch for adding OFONO_VENDOR_TELIT first. We do
not really wanna intermix plugins/ and drivers/ patches.

You should not need this. The chat should be unreferenced in
telit_disable.
And oFono core will ensure that the modem gets disabled before remove
callback is called.

Variable declarations and code should be separate by an empty line. So
please add an extra empty line here.

This is not good at all. You are sleeping in a single-threaded event
driven daemon for a second.
If the modem is broken and is not ready right away after this
notification comes in, then you need to trigger this via
g_timeout_add_seconds().

We do not use empty return statements. Just remove this one.

I think you want to extract the actual SIM insert handling into a
separate function and just call it from telit_qss_cb and
telit_qss_notify.

If modem enabling fails, you should actually unreference the chat object
here and more important return here.

We should be using a none_prefix here, but not all plugins do this. So
if you wanna help us, then please send patches for fixing the other
modem plugins as well ;)

No need to check for data->chat here. If that happens, then something is
seriously broken ;)

In general rule of style, please move netreg atom to the top. It will
not change functionality, but is just a good style.
