[PATCH 4.14 01/37] pwm: cros-ec: Explicitly set .polarity in .get_state()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

[ Upstream commit 30006b77c7e130e01d1ab2148cc8abf73dfcc4bf ]

The driver only supports normal polarity. Complete the implementation of
.get_state() by setting .polarity accordingly.
