+Subject: pwm: hibvt: Explicitly set .polarity in .get_state()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+commit 6f57937980142715e927697a6ffd2050f38ed6f6 upstream.
+
+The driver only both polarities. Complete the implementation of
+.get_state() by setting .polarity according to the configured hardware
+state.
+
+Fixes: d09f00810850 ("pwm: Add PWM driver for HiSilicon BVT SOCs")
