From 576b8aa079388d2151f396bb947cf0a8e5ba255e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 7 Oct 2019 21:08:19 +0300 Subject: libcamera: controls: Store control name in ControlId MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ControlId class stores a pointer to the control name. This works fine for statically-defined controls, but requires code that allocates controls dynamically (for instance based on control discovery on a V4L2 device) to keep a list of control names in separate storage. To ease usage of dynamically allocated controls, store a copy of the control name string in the ControlId class.
