Nicholas Kazlauskas f638d7505f drm/amd/display: Fix deadlock when falling back to v2 from v3 ... [Why] A deadlock in the kernel occurs when we fallback from the V3 to V2 add_topology_to_display or remove_topology_to_display because they both try to acquire the dtm_mutex but recursive locking isn't supported on mutex_lock(). [How] Make the mutex_lock/unlock more fine grained and move them up such that they're only required for the psp invocation itself.
