A fix is available — apply it.

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.
