From aafa406edd39d04689bfcd4ff5239f918a0885ce Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Wed, 16 Oct 2024 20:19:41 +0900 Subject: libcamera: controls: Add vendor information to ControlId Add vendor/namespace information to ControlId, so that the vendor can be queried from it. This is expected to be used by applications either simply to display the vendor or for it to be used for grouping in a UI.
