[v6,071/164] pwm: meson: Make use of pwmchip_parent() accessor

Message ID 02d5f32001c4d0817fa79f5831cfd16b7e345f00.1707900770.git.u.kleine-koenig@pengutronix.de (mailing list archive)

Series pwm: Improve lifetime tracking for pwm_chips | expand

struct pwm_chip::dev is about to change. To not have to touch this
driver in the same commit as struct pwm_chip::dev, use the accessor
function provided for exactly this purpose.
