From b12e4fd5f3e4852cdb1fa11d1a48498bea9e92cf Mon Sep 17 00:00:00 2001 From: Azhar Shaikh Date: Fri, 21 Aug 2020 14:47:23 -0700 Subject: [PATCH] platform/chrome: cros_ec_typec: Avoid setting usb role twice during disconnect On disconnect port partner is removed and usb role is set to NONE. But then in cros_typec_port_update() the role is set again. Avoid this by moving usb_role_switch_set_role() to cros_typec_configure_mux().
