From 109a98e8c07b57a4676bf62dbba59cba670163c8 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Tue, 19 Oct 2021 17:17:51 +0530 Subject: camera_device: Remove private scope of Camera3RequestDescriptor Camera3RequestDescriptor is a utility structure that groups information about a capture request. It can be and will be extended to preserve the context of a capture overall. Since the context of a capture needs to be shared among other classes (for e.g. CameraStream) having a private definition of the struct in CameraDevice class doesn't help. Hence, de-scope the structure so that it can be shared with other components (through references or pointers). Splitting the structure to a separate file will help avoiding circular dependencies when using it through the HAL implementation.
