Subject[PATCH] usb: misc: eud: Fix an error handling path in eud_probe()
Date
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().

Fixes: 9a1bf58ccd44 ("usb: misc: eud: Add driver support for Embedded USB Debugger(EUD)")
