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.

commit 525cb7ba6661074c1c5cc3772bccc6afab6791ef upstream.

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.
