This one looks to need a bit of tweaking yet though ... probably that could be done after merge. The state can need changing after one of the drivers is unregistered; using __exit not __devexit is likely wrong (especially given your MUSB patchlet); xceiv_to_nop() should be an inline function; check otg_set_transceiver() value; don't bother with dev_info(); and I'm not quite sure of the methods. Plus I think it's probably best to include a utility that board init code can call to register the NOP transceiver device ... instead of cloning that bit of code (in your second patch) into every board-*.c file that needs it. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
