Hi, This patchset fixes suspend/resume support in pwm-samsung driver (which has an effect of fixing suspend/resume support for PWM client drivers such as pwm-fan one). Then it removes no longer needed suspend/resume code from pwm-fan driver. It was tested on Odroid-XU3 board (with few extra patches adding SoC/board suspend/resume support which are not in upstream yet). The initial issue that has been observed on this configuration was that after suspend/resume operation the fan was turned on (while the thermal code had explicitly disabled the fan by calling back into pwm-fan driver before the suspend/resume). Fixing this in the pwm-fan driver itself is not feasible since pwm_config()/pwm_disable() & co. API saves information about current state and doesn't pass the relevant values to PWM core if they are identical to the ones used previously (moreover PWM core itself does the same before calling into the PWM hardware driver).
