929b22e669 usb: misc: eud: Fix an error handling path in eud_probe()
It is odd to call devm_add_action_or_reset() before calling the function
that should be undone.

Either, the "_or_reset" part should be omitted, or the action should be
recorded after the resources have been allocated.

Switch the order of devm_add_action_or_reset() and usb_role_switch_get().

9a1bf58ccd usb: misc: eud: Add driver support for Embedded USB Debugger(EUD)
Add support for control peripheral of EUD (Embedded USB Debugger) to
listen to events such as USB attach/detach, pet EUD to indicate software
is functional.Reusing the platform device kobj, sysfs entry 'enable' is
created to enable or disable EUD.

To enable the eud the following needs to be done
echo 1 > /sys/bus/platform/.../enable

To disable eud, following is the command
echo 0 > /sys/bus/platform/.../enable
