SubjectRe: [PATCH v1 1/4] pwm: sysfs: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()
Hello,

Tested on ARCH=arm allmodconfig: No change in the binary (as expected I
think). When disabling PM_SLEEP the resulting change of this patch looks
as follows:

add/remove: 0/1 grow/shrink: 0/0 up/down: 0/-92 (-92)
Function old new delta
pwm_class_pm_ops 92 - -92
Total: Before=5213, After=5121, chg -1.76%

Looks like a quest to convert all SIMPLE_DEV_PM_OPS users to
DEFINE_SIMPLE_DEV_PM_OPS.
