This patch fixes the panel on my device (paz00). Can it be applied to 2019-07 ?

Thx in advance

Fixes: 57e7775413 ("video: backlight: Parse PWM polarity cell")

set_pwm will always fail if pwm_set_invert is not implemented, leaving the backlight dark. Fix this by calling pwm_set_invert only if pwm is inverted.
