mac80211: make LED triggering depend on activation When LED triggers are compiled in, but not used, mac80211 will still call them to update the status. This isn't really a problem for the assoc and radio ones, but the TX/RX (and to a certain extend TPT) ones can be called very frequently (for every packet.) In order to avoid that when they're not used, track their activation and call the corresponding trigger (and in the TPT case, account for throughput) only when the trigger is actually used by an LED. Additionally, make those trigger functions inlines since theyre only used once in the remaining code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

leds: Change led_trigger_blink[_oneshot]() delay parameters to pass-by-value led_blink_set[_oneshot]()'s delay_on and delay_off function parameters are pass by reference, so that hw-blink implementations can report back the actual achieved delays when the values have been rounded to something the hw supports. This is really only interesting for the sysfs API / the timer trigger. Other triggers don't really care about this and none of the callers of led_trigger_blink[_oneshot]() do anything with the returned delay values. Change the led_trigger_blink[_oneshot]() delay parameters to pass-by-value, there are 2 reasons for this: 1. led_cdev->blink_set() may sleep, while led_trigger_blink() may not. So on hw where led_cdev->blink_set() sleeps the call needs to be deferred to a workqueue, in which case the actual achieved delays are unknown (this is a preparation patch for the deferring). 2. Since the callers don't care about the actual achieved delays, allowing callers to directly pass a value leads to simpler code for most callers.
