Does this mean that 4.14 backport doesn't have the WWAN subsystem support? I truly believed it would have had it, or so I was told by some dev team that had tested it. Sorry if that's not the case :/ If so, it would mean the backport from that repo isn't usable for MM. I have my own patch-by-patch backport to 5.4 including the wwan subsystem, but haven't tried to go back further yet, not sure how complex that would be to include everything for 4.14. Not sure if I'm missing something, but I definitely wouldn't have expected the mhi0_QMI port name. -- Aleksander https://aleksander.es
