Mainline Linux kernel for the Jolla C2

I’ve uploaded a new version in which voice calls should work. However, VoLTE is not working yet, and it seems that the phone cannot fall back to 2G/3G unless the call is initiated by the user.

I was hoping to get the “Network mode” switch working in settings so that you can at least switch 4G off manually, but for some reason the modem fails to power off its LTE hardware and crashes when the setting is changed (or when flight mode is enabled):

The network technology switch is disabled for now, which means that you cannot receive incoming calls when a 4G network is available.
