[PATCH 5.15 26/93] pwm: sprd: Explicitly set .polarity in .get_state()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

[ Upstream commit 2be4dcf6627e1bcbbef8e6ba1811f5127d39202c ]

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

Fixes: 8aae4b02e8a6 ("pwm: sprd: Add Spreadtrum PWM support")
