extcon: max77693: Use resource managed interrupt line
Use resource managed interrupt line devm_request_threaded_irq() to simplify a little cleanup paths: - no goto to cleanup label, - simpler remove function. Overall the driver size is decreased by 11 line of code. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
