Sorry, I misread your message.  You are setting the device's flag, not

Never mind.

This still doesn't help in this case where CONFIG_PM_RUNTIME is

Yes, it's better to set the flag during every device reset now.

Also pppoe or network interface over serial port is a bit difficult to
deal with, as Oliver pointed out.
