[v6,065/164] pwm: lpss: Make use of pwmchip_parent() accessor

Message ID 77617ba84bed7807a05779109432a292dd79f72f.1707900770.git.u.kleine-koenig@pengutronix.de

Series pwm: Improve lifetime tracking for pwm_chips | expand

Commit Message

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.
