From 514acf1cefd020eb21d7c180050a8d66b723d2d8 Mon Sep 17 00:00:00 2001 From: Prashant Malani Date: Thu, 29 Oct 2020 15:27:34 -0700 Subject: [PATCH] platform/chrome: cros_ec_typec: Clear partner identity on device removal The partner identity struct isn't reset when a partner is removed, meaning a subsequent partner can inherit an old partner's identity VDOs before discovery is complete. So, clear that struct when a partner removal is detected.
