## Description

In the Linux kernel, the following vulnerability has been resolved:  platform/chrome: cros_ec_typec: Init mutex in Thunderbolt registration  cros_typec_register_thunderbolt() missed initializing the `adata->lock` mutex.  This leads to a NULL dereference when the mutex is later acquired (e.g. in cros_typec_altmode_work()).  Initialize the mutex in cros_typec_register_thunderbolt() to fix the issue.
