[PATCH 3/3] hwmon: pwm-fan: remove no longer needed suspend/resume code

From: Bartlomiej Zolnierkiewicz
Date: Mon Apr 03 2017 - 09:48:03 EST


The suspend/resume is now properly handled by pwm-samsung driver
(pwm-fan is currently only used by ARM Exynos boards) and the old
code only handles ctx->pwm_value != 0 case. Just remove it.
