Hans Verkuil 958c7c7e65 [media] v4l2-ctrls: fix corner case in round-to-range code 
If you have a maximum that is at the limit of what the type supports,
and the step is > 1, then you can get wrap-around errors since the
code assumes that the maximum that the type supports is
ctrl->maximum + ctrl->step / 2.

In practice this is always fine, but in artificially crafted ranges
you will hit this bug. Since this is core code it should just work.

This bug has always been there but since it doesn't cause problems in
practice it was never noticed.
