[libcamera-devel] [PATCH 0/8] libcamera: improve validation of camera operations

[Niklas Söderlund]

Hi,

This series fix a few bugs in the camera as well as introduce a state 
machine to better keep track on what applications can do with a camera 
at any given point in its life cycle. As well as add a few new checks to 
catch problems early.

See individual patches for detailed descriptions. Some of these patches 
could be posted separately but as they all conflict with etch other I 
chose to keep them all together. If necessary or requested I might break 
some parts out or merge parts of this series as the review process 
progress and allows.

Niklas Söderlund (8):
  libcamera: camera: fix bug in error check for streamConfiguration()
  libcamera: align the documentation for numeric error codes
  libcamera: camera: document return values for application facing
    functions
  cam: fix order camera is operated on
  libcamera: camera: add state machine to control access from
    applications
  libcamera: store stream pointers in sets instead of a vectors
  libcamera: camera: ensure streams belong to camera
  libcamera: camera: make sure camera is configured before starting
