[libcamera-devel] [PATCH v2 0/5] libcamera: Control framework backend rewor

[Jacopo Mondi]

Updated version of DataValue and DataInfo series, with comments from Kieran
taken in.

Question on the Control and V4L2Control classes API are still open (see v1 cover
letter)

v1 -> v2:
  1/1 -> remove rougue #if 0
      -> remove copy constructor
      -> use sizeof(type) for DataSize
  2,3,4 -> spelling and minor updates
  5/5 -> Fix comments about undefined behaviour
      -> s/Control/ControlValue
      -> still a few open points in kieran's comments:
	 - s/update/merge
         - mentioning of gen-controls.awk in ControlMetadata documentation

Thanks
