From f1bd5eae7de76ef8eabc9e393f5a8718d8f25d2a Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Delgado Date: Mon, 4 Nov 2019 14:09:19 +0100 Subject: media: v4l2_ctrl: Add const pointer to ctrl_ptr This pointer is used to point to data that is constant. Thanks to this we can avoid a lot of casting and we make more clear when the data is constant or variable.
