`last_repeat` holds the actual value requested by the user whereas
`repeat` is a software iteration variable that is unused in hardware
patterns.
Furthermore `last_repeat` is the field returned to the user when reading
the `repeat` sysfs property. This field is initialized to `-1` which is
- together with `1` - the only valid value in the upcoming Qualcomm LPG
driver. It is thus unexpected when `repeat` with an initialization
value of `0` is passed into the the driver, when the sysfs property
clearly presents a value of `-1`.

Thanks for picking up Bjorn's LPG patch into your tree! Will you also
be able to pick up this patch to accompany it?
