ARM: 6281/1: video/imxfb.c: allow usage without BACKLIGHT_CLASS_DEVICE
From: Eric Bénard <eric@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)
