Subject: [PATCH] platform/chrome: cros_ec_typec: Correct alt mode index
Git-commit: 4e477663e396f48c5cfc5f2d75d4b514f409516a
Patch-mainline: v6.1-rc1
References: git-fixes
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")
