From: Eric Bénard <96f164ad4d9b2b0dacf8ebee2bb1eeb3aa69adf1@eukrea.com>

This fixes the following build failure:

	drivers/built-in.o: In function `imxfb_probe': mxcmmc.c:(.init.text+0xd04): undefined reference to `backlight_device_register'
	drivers/built-in.o: In function `imxfb_remove': mxcmmc.c:(.devexit.text+0x44): undefined reference to `backlight_device_unregister'

that was introduced by

	7a2bb23 (imxfb: add pwmr controlled backlight support)
