The DSI-CM driver uses the backlight class so needs to build depend on it.

I checked that the following build errors are removed.
drivers/video/omap2/displays-new/panel-dsi-cm.c:1257: undefined reference to `backlight_device_register'
drivers/video/omap2/displays-new/panel-dsi-cm.c:1283: undefined reference to `backlight_device_unregister'
drivers/built-in.o: In function `dsicm_remove':

Thank you.

Thanks, I'll queue for 3.12 fixes.
I wish we could "select" instead of "depends on"...

I'm not so sure.
If we select BACKLIGHT_CLASS_DEVICE, we could end up compiling
backlight.c without fbdev, and backlight.c uses fb's funcs.
The funny thing is, there is FB_BACKLIGHT, which seems to be designed to
be selectable (and is selected). That one depends on FB, but if I'm not
mistaken, that dependency does not do anything if FB_BACKLIGHT is selected.
FB_BACKLIGHT in turn selects both BACKLIGHT_LCD_SUPPORT and
BACKLIGHT_CLASS_DEVICE, neither of which seem to be designed to be
selectable.
I think that's a bit broken. Anyway, I guess it's better to "depend on"
here, to be on the safe side.
