Re: [MM] [PATCH] iface-modem: fix a crash due to removed signal_quality_check context

[Aleksander Morgado <aleksander lanedo com>]

Good catch :-)

Are you able to update the patch including the same fix for the access
technologies loading? Suffers from the same issue.

Also, if the context is not anymore available because we
disabled/shutdown the interface, I wouldn't also set the values
retrieved (e.g. skip calling
mm_iface_modem_update_[signal_quality|access_technologies]).
