Subject: drivers/misc/apds9802als.c: put the device into runtime suspend after resume()/probe() is handled
From: Hong Liu <hong.liu@xxxxxxxxx>
Put the device into runtime suspend after resume()/probe() is handled by
the PM core and the device core code. No need to manually add them in
each single driver. And correct the runtime state in remove().
