pwm: sprd: Explicitly set .polarity in .get_state()
The driver only supports normal polarity. Complete the implementation of .get_state() by setting .polarity accordingly. Fixes: 8aae4b02e8a6 ("pwm: sprd: Add Spreadtrum PWM support") Link: https://lore.kernel.org/r/20230228135508.1798428-5-u.kleine-koenig@pengutronix.de Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
