Subject: extcon: Fix signedness bugs about break error handling
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit a598af7f0279195abffbfb9bf2070457e9c89ff3 upstream.
Unsigned is never less than zero so this error handling won't work.
Fixes: be052cc87745 ('extcon: Fix hang and extcon_get/set_cable_state().')
