pwm: Return -EINVAL for old-style drivers without .set_polarity callback
Since commit 2b1c1a5d5148 ("pwm: Use -EINVAL for unsupported polarity") all drivers implementing the apply callback are unified to return -EINVAL if an unsupported polarity is requested. Do the same in the compat code for old-style drivers. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
