PM: Remove power_state.event checks from suspend core code
The suspend routines should be called for every device during a system sleep transition, regardless of the device's state, so that drivers can regard these method calls as notifications that the system is about to go to sleep, rather than as directives to put their devices into the 'off' state. This is documented in Documentation/power/devices.txt and is already done in the core resume code, so it seems reasonable to make the core suspend code behave accordingly. Signed-off-by: Rafael J.
