The only side effect of this change is that pwm->state.polarity is initialized to PWM_POLARITY_NORMAL instead of PWM_POLARITY_INVERSED. However all other members of pwm->state are uninitialized and consumers are expected to provide the right polarity (either by setting it explicitly or by using a helper like pwm_init_state() that overwrites .polarity anyhow with a value independent of the initial value). The eventual goal is to remove pwmchip_add_with_polarity() and so simplify the data flow in the PWM core.
