Hi,
I was testing my huawei disconnect patch on top of commit ca41d63a305c.
Basically I was just connecting and disconnecting in a row from connman
and ofono crashed:

As Denis has pointed out, we can add a check for gcd->ppp in at_gprs_context_remove() to avoid this crash.
When I tried to activate & deactivate context on my Huawei EM770W modem, I see kernel module usb_serial warning.

When I shutdown the oFono, kernel reports:
tty_port_close_start: tty->count = 1 port count = 0.
Any ideas?

I observed the warning shows up when /dev/ttyUSB2 send us any intermediate result. If I remove gprs atom and recreate it in huawei_disconnect, the kernel warning is gone. Does anyone see the same problem in other Huawei modem? If not, I assume it's a problem only for EM770 modem. (I don't have other Huawei modem at hand)
Thanks,
