Subject: [PATCH] leds: leds-asic3: make LEDS_ASIC3 depend on LEDS_CLASS
Date: Wed, 25 May 2011 13:19:40 +0800 [thread overview]
Message-ID: <1306300780.20042.7.camel@phoenix> (raw)
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
