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.
