Summary
usb: typec: ucsi: displayport: Fix deadlock
Details

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

usb: typec: ucsi: displayport: Fix deadlock

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