[media] media: au0828 enable the right media source when input changes
Change vidioc_s_input() to enable the media source for the newly selected input. v4l2-core enables source before calling au0828's vidioc_s_input() handler. Hence, when input selection changes, media source for the newly selected input needs to be enabled. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
