2.6.34-stable review patch. If anyone has any objections, please let me know.

------------------

From: Randy Dunlap <randy.dunlap@oracle.com>

commit 89a7644be2c59eea443b0db2514fd42d5de909f8 upstream.

eeepc-wmi uses backlight*() interfaces so it should depend on
BACKLIGHT_CLASS_DEVICE.

eeepc-wmi.c:(.text+0x2d7f54): undefined reference to `backlight_force_update'
eeepc-wmi.c:(.text+0x2d8012): undefined reference to `backlight_device_register'
eeepc-wmi.c:(.devinit.text+0x1c31c): undefined reference to `backlight_device_unregister'
eeepc-wmi.c:(.devexit.text+0x2f8b): undefined reference to `backlight_device_unregister'
