Subject: leds: fix up dependencies
From: Johannes Berg <johannes.berg@xxxxxxxxx>
5ada28bf76752 ("led-class: always implement blinking") causes the
following compilatation error:
LD .tmp_vmlinux1
drivers/built-in.o: In function `led_trigger_set':
drivers/leds/led-triggers.c:116: undefined reference to `led_brightness_set'
It's not useful to build LED triggers when there are no LEDs that can be
triggered by them. Therefore, fix up the dependencies so that this cannot
happen, and fix a few users that select triggers to depend on LEDS_CLASS
as well (there is also one user that also selects LEDS_CLASS, which is
OK).
As a result, we can now make everything a module again if desired
(including the LED triggers, which previously could only be built in) --
and add back the warning in rt2x00's Kconfig I previously removed.
