Modem Manager bring up

[Senthil Kumaresan]

Hi Aleksander,

Ok. Anyway, I am backporting the last mhi driver from Linux 5.15 to 4.19. I
have compiled the driver successfully and loaded it to the target.
The /dev/wwan0qmi0 is not there, because I did not take the
drivers/net/wwan directory. I need to take them and rebuild and see whether
the ModemManager is coming up or not.

Thanks,
Senthil
