I follow the argument for class drivers. But this patch also
modifies drivers for specific existing USB 2.0 only devices
which are unlikely to ever grow USB 3.0 support, such as the
Gigaset ISDN driver:

>  drivers/isdn/gigaset/bas-gigaset.c            |    1 +
>  drivers/isdn/gigaset/usb-gigaset.c            |    1 +

What is the interest of setting the disable_hub_initiated_lpm
flag for these?

Thanks,
Tilman
