From a07968bed27638f799adb825266a8417f6f3cdb3 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 22 Oct 2022 23:53:26 +0300 Subject: libcamera: pipeline_handler: Return unique_ptr from generateConfiguration() The PipelineHandler::generateConfiguration() function allocates a CameraConfiguration instance and returns it. The ownership of the instance is transferred to the caller. This is a perfect match for a std::unique_ptr<>, which the Camera::generateConfiguration() function already returns. Update PipelineHandler::generateConfiguration() to match it. This fixes a memory leak in one of the error return paths in the IPU3 pipeline handler. While at it, update the Camera::generateConfiguration() function documentation to drop the sentence that describes the ownership transfer, as that is implied by usage of std::unique_ptr<>.
