Subject[RESEND PATCH] leds: ledtrig-pattern: Use last_repeat when applying hw pattern
Date
`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`.

Resending to pick up Bjorn's s-o-b/r-b and address Pavel in the To:
field directly.
