Subject: [media] media: au0828 set ctrl_input in au0828_s_input() Author: Shuah Khan <[email protected]> Date: Fri Feb 12 21:18:03 2016 -0200 dev->ctrl_input is set in vidioc_s_input() and doesn't get set in au0828_s_input(). As a result, dev->ctrl_input is left uninitialized until user space calls s_input. It works correctly because the default input value is 0 and which is what dev->ctrl_input gets initialized via kzalloc(). Change to set dev->ctrl_input in au0828_s_input(). Also optimize vidioc_s_input() to return if the new input value is same as the current.
