[PATCH 2/4] platform/chrome: cros_ec_typec: Correct alt mode index
From: Prashant Malani
Date: Fri Aug 19 2022 - 15:08:53 EST
Alt mode indices used by USB PD (Power Delivery) start with 1, not 0.
Update the alt mdoe registration code to factor this in to the alt mode
descriptor.
Fixes: de0f49487db3 ("platform/chrome: cros_ec_typec: Register partner altmodes")
