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

From: Christophe JAILLET
Date: Sun Apr 03 2022 - 05:59:29 EST


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().
