Hello,

Those two small patches clean up the MediaDevice and PipelineHandler
locking. The goal is to prepare for concurrent usage of multiple cameras
exposed by the same pipeline handler (on platforms that support this),
and to fix a thread-safety issue.

Please see individual patches for details.

Laurent Pinchart (2):
  libcamera: media_device: Move recursive lock handling to pipeline
    handler
  libcamera: pipeline_handler: Make lock() and unlock() thread-safe
