$ git grep vidioc_s_ctrl
drivers/media/radio/radio-wl1273.c:static int wl1273_fm_vidioc_s_ctrl(struct v4l2_ctrl *ctrl)
drivers/media/radio/radio-wl1273.c:     .s_ctrl = wl1273_fm_vidioc_s_ctrl,

Now that s_ctrl is the callback of the control handler ops, but
I think it is wise if you add a patch that renames wl1273_fm_vidioc_s_ctrl to wl1273_fm_s_ctrl.

Just so the string 'vidioc_s_ctrl' no longer exists in the code base.
Besides, it isn't the correct name of this function anyway. It's clearly a left-over
from the past.
