Subject: [PATCH 5.15 224/530] platform/chrome: cros_ec_typec: Correct alt mode index
From: Prashant Malani <pmalani@...omium.org>
[ Upstream commit 4e477663e396f48c5cfc5f2d75d4b514f409516a ]
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")
