    Added Description In the Linux kernel, the following vulnerability has been resolved:

    usb: typec: ucsi: displayport: Fix deadlock

    This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock
    functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector
    mutex is only locked if a connection is established and the partner pointer
    is valid. This resolves a deadlock scenario where
    ucsi_displayport_remove_partner holds con->mutex waiting for
    dp_altmode_work to complete while dp_altmode_work attempts to acquire it.
