[PATCH v2 2/4] pwm: sysfs: Return directly from the for-loop in PM callbacks

From: Andy Shevchenko
Date: Fri Aug 26 2022 - 13:07:25 EST


There is no need to assign ret to 0 and then break the loop just
for returning the error to the caller. Instead, return directly
from the for-loop, and 0 otherwise.
