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.

power: supply: leds: Fix blink to LED on transition When a battery's status changes from charging to full then the charging-blink-full-solid trigger tries to change the LED from blinking to solid/on. As is documented in include/linux/leds.h to deactivate blinking / to make the LED solid a LED_OFF must be send: """ * Deactivate blinking again when the brightness is set to LED_OFF * via the brightness_set() callback. """ led_set_brighness() calls with a brightness value other then 0 / LED_OFF merely change the brightness of the LED in its on state while it is blinking. So power_supply_update_bat_leds() must first send a LED_OFF event before the LED_FULL to disable blinking.

power: move power supply drivers to power/supply This moves all power supply drivers from drivers/power/ to drivers/power/supply/. The intention is a cleaner source tree, since drivers/power/ also contains frameworks unrelated to power supply, like adaptive voltage scaling. Signed-off-by: Sebastian Reichel <sre@kernel.org>
