[v4,019/115] pwm: jz4740: Make use of pwmchip_parent() macro

Message ID e52d09b461b13e9aaeb989ceeaf2360ec66720ac.1701860672.git.u.kleine-koenig@pengutronix.de (mailing list archive)

Series pwm: Fix lifetime issues 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 macro
provided for exactly this purpose.
