Subject: [media] media: v4l2-ctrls: Fix 64bit support in get_ctrl() Author: Benoit Parrot <[email protected]> Date: Mon Sep 21 13:03:21 2015 -0300 When trying to use v4l2_ctrl_g_ctrl_int64() to retrieve a V4L2_CTRL_TYPE_INTEGER64 type value the internal helper function get_ctrl() would prematurely exit because for this control type the 'is_int' flag is not set. This would result in v4l2_ctrl_g_ctrl_int64 always returning 0. Also v4l2_ctrl_g_ctrl_int64() is reading and returning the 32bit value member instead of the 64bit version, so fixing that as well. This patch extends the condition check to allow the V4L2_CTRL_TYPE_INTEGER64 type to continue processing instead of exiting.
