Pull pwm fix from Uwe Kleine-König:
 "Fix an off-by-one in the stm32 driver.

  Hardware engineers tend to start counting at 1 while the software guys
  usually start with 0. This isn't so nice because that results in
  drivers where pwm device #2 needs to use the hardware registers with
  index 3.

  This was noticed by Fabrice Gasnier.

  A small patch fixing that mismatch is the only change included here"
