Oh right, it used to be a macro, but I changed that. I made the commit
log read:

    pwm: Provide an inline function to get the parent device of a given chip

    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 function should be used in all
    drivers directly accessing chip->dev now. This way struct pwm_chip and
    this new function can be changed without having to touch all drivers in
    the same change set.

Thanks,
Uwe
