[PATCH v2 1/1] usb: typec: ucsi: Don't warn on probe deferral

From: Wayne Chang
Date: Tue Sep 27 2022 - 08:30:04 EST


Deferred probe is an expected return value for fwnode_usb_role_switch_get().
Given that the driver deals with it properly, there's no need to output a
warning that may potentially confuse users.
