[libcamera-devel] [PATCH] libcamera: request: Facilitate retrieval of the camera

[Kieran Bingham]

Provide a means of identifying the Camera object which created the Request.

This allows identifying the correct Camera device to work with in completion
callbacks which are not otherwise wrapped with a means to identify the
Camera responsible for completion.
