Subject: pwm: dwc-core: Make use of pwmchip_parent() accessor
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4839f5a7c49a13dcfc3aaa3da87b26e9884488a9;p=linux.git

pwm: dwc-core: Make use of pwmchip_parent() accessor

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.
