[ Upstream commit 73278d483378cf850ade923a1107a70297b2602a ]
The patch adding support for dynamically allocated arrays accidentally dropped the line setting ctrl->is_new to 1, thus new string values were always ignored.
Fixes: fb582cba4492 ("media: v4l2-ctrls: add support for dynamically allocated arrays.")
