Subject: drivers/leds/leds-asic3: make LEDS_ASIC3 depend on LEDS_CLASS
X-Git-Tag: v3.0~257
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9d8f776bfb812dd23fcdbb698e9ac4298fc3c624;p=platform%2Fkernel%2Flinux-amlogic.git

drivers/leds/leds-asic3: make LEDS_ASIC3 depend on LEDS_CLASS

We call led_classdev_unregister/led_classdev_register in
asic3_led_remove/asic3_led_probe, thus make LEDS_ASIC3 depend on
LEDS_CLASS.

This patch fixes below build error if LEDS_CLASS is not configured.

    LD      .tmp_vmlinux1
  drivers/built-in.o: In function `asic3_led_remove':
  clkdev.c:(.devexit.text+0x1860): undefined reference to `led_classdev_unregister'
  drivers/built-in.o: In function `asic3_led_probe':
  clkdev.c:(.devinit.text+0xcee8): undefined reference to `led_classdev_register'
  make: *** [.tmp_vmlinux1] Error 1
