Subject: [PATCH 6.0 837/862] usb: typec: ucsi: Dont warn on probe deferral

From: Wayne Chang <waynec@...dia.com>

[ Upstream commit fce703a991b7e8c7e1371de95b9abaa832ecf9c3 ]

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.
