Uwe Kleine-König 322b70b522 pwm: lpc32xx: Don't modify HW state in .probe() after the PWM chip was registered ... commit 3d2813fb17 upstream. This fixes a race condition: After pwmchip_add() is called there might already be a consumer and then modifying the hardware behind the consumer's back is bad. So set the default before. (Side-note: I don't know what this register setting actually does, if this modifies the polarity there is an inconsistency because the inversed polarity isn't considered if the PWM is already running during .probe().)
