Currently a pwm_chip stores in its struct device *dev member a pointer to the parent device. Preparing a change that embeds a full struct device in struct pwm_chip, this accessor macro should be used in all drivers directly accessing chip->dev now. This way struct pwm_chip and this macro can be changed without having to touch all drivers in the same change set. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
