[PATCH 1/1] extcon: gpio: queue work only if debounce is NZ

[Venkat Reddy Talla <vreddytalla@nvidia.com>]

Use queue_delayed_work only when debounce time is
required to read gpio state properly, read the gpio
state and set the extcon cable state in IRQ handler
context if gpio settling time is not needed.
