Subject: [patch] ACER_WMI/ASUS_LAPTOP: fix build bug


randconfig testing in x86.git found the following upstream build bug:

 drivers/built-in.o: In function `acer_led_exit':
 acer-wmi.c:(.text+0xdc76e): undefined reference to `led_classdev_unregister'
 drivers/built-in.o: In function `acer_platform_probe':
 acer-wmi.c:(.devinit.text+0x63e6): undefined reference to `led_classdev_register'

which was due to acer-wmi.o only depending on CONFIG_LEDS_CLASS, while 
also using a symbol offered by CONFIG_NEW_LEDS. Also fix a similar bug 
in CONFIG_ASUS_LAPTOP.
